Abstract
A frame (A) of a diagnostic imaging device such as a CT scanner or an MRI device has a bore defining a patient examination region (12). A first x-ray source (B) is mounted to a frame (C) for rotation around the examination region (12). An arc of first radiation detectors (14) detects x-rays which have traversed the examination region. A first image reconstruction processor (18) reconstructs a tomographic image representation from signals generated by the first radiation detectors. A fluoroscopy device (D) is mechanically coupled to the diagnostic scanner for generating and displaying at least substantially real-time fluoroscopic projection image representations on a display monitor (60). A second x-ray source (32) transmits x-rays to an amorphous silicon flat panel radiation detector (36). A second image reconstruction processor (58) reconstructs the fluoroscopic projection image representations from signals generated by the flat panel radiation detector (36). A C-arm (30) supports the second x-ray source (32) and the flat panel radiation detector (36) in a plane offset from a plane of the C-arm. A movable mounting structure (E) is mechanically connected with the gantry (A) and the C-arm (30) to move the C-arm between a stored position and an operating position adjacent the bore.
Description
- The present invention relates to the medical diagnostic imaging arts. It finds particular application in conjunction with a diagnostic imaging device such as a computerized tomographic (CT) scanner and a Magetic Resonace Imaging (MRI) apparatus, which includes a fluoro-assist device, and will be described with particular reference thereto. However, it should be appreciated that the present invention may also find application in conjunction with other multi-modality medical imaging systems such as nuclear medicine scanners, etc. where a fluoro-assist device may be useful.
- When performing minimally invasive or certain interventional procedures such as abscess drainages, CT arterial portography, TIPS, and catheter placement for organ assessment, catheters are typically placed or positioned in a patient in a fluoroscopy room or suite. The patient, with the catheter in place, is then moved to a CT suite where the procedure is then performed.
- A number of disadvantages exist when moving a patient between a fluoroscopy suite and a CT suite. For instance, the danger exists that the catheter may move or shift within the patient during transport from the fluoroscopy suite to the CT suite. Further, the scheduling and availability of both suites can be complicated. In other cases, when a lesion is diagnosed during a CT procedure, the patient must then be rescheduled for a needle biopsy, or the biopsy is performed with the CT scanner alone, which is complicated and takes a long time to perform.
- It is known to use a mobile C-arm fluoroscopy device to provide fluoro images during interventional procedures performed in a CT suite. However, mobile C-arm fluoroscopy devices are not always available when needed. In addition, known C-arm fluoroscopy devices, including mobile C-arm fluoroscopy devices, use large, cylindrical image intensifier tubes which are difficult to maneuver and position adjacent a CT gantry.
- Further, the interventionalist must stand beside the image intensifier tube to access the patient during an interventional procedure, which may be an awkward position for the interventionalist and which also increases the radiation dose to the interventionalist. It is also known that image intensifier tubes tend to introduce image distortion due to the glass curvature and magnetic effects. Present mobile C-arms are big and bulky, and because of their size, they are difficult to store, and are typically in the way when not in use.
- It is known to use a CT system to provide a fluoro image for interventional work. However, using the CT system for fluoro imaging requires a physician to work on the patient in the bore of the CT gantry which is awkward for the physician, and which generates a significantly higher radiation dose to both the patient and the surgeon. Further, the CT system can only produce fluoro images which are in the same plane as the CT system.
- It is also known to rotate, pivot, or swing a common patient support between a CT scanner and an angiographic (i.e., fluoroscopic) unit. However, the patient is still moved when the patient support is rotated between the two pieces of diagnostic equipment. In addition, linking a separate CT scanner with an angiographic unit via a common, rotatable, patient support is an expensive alternate solution.
- Accordingly, it has been considered desirable to develop a new and improved fluoro assist feature for an imaging system which meets the above-stated needs and overcomes the foregoing difficulties and others while providing better and more advantageous results.
- In accordance with one aspect of the present invention, a diagnostic imaging apparatus is disclosed. The diagnostic imaging apparatus includes a frame defining an examination region. A diagnostic imaging subsystem generates first diagnostic image representations of an object when the object is positioned within the examination region. A patient support is adapted for movement through the examination region. A fluoroscopic imaging subsystem generates fluoroscopic image representations of the object. The fluoroscopic imaging subsystem includes an x-ray source for transmitting x-rays, a flat panel image receptor for detecting the x-rays and generating signals indicative of the detected x-rays, and a support member for supporting the flat panel image receptor in a stored position remote from the patient support and an operating position proximate the patient support.
- In accordance with another aspect of the present invention, a diagnostic imaging apparatus is disclosed. The diagnostic imaging apparatus includes a frame defining an examination region, a diagnostic imaging subsystem for generating a first diagnostic image representation of an object when the object is positioned within the examination region, and a patient support adapted for movement through the examination region. A fluoroscopic imaging subsystem is mechanically coupled to the frame, and includes a flat panel image receptor which detects x-rays and generates signals indicative of the detected x-rays.
- In accordance with yet another aspect of the present invention, a method of generating fluoroscopic projection image representations with a diagnostic imaging apparatus, is disclosed. The diagnostic imaging apparatus includes a frame defining an examination region, a first diagnostic imaging subsystem for generating diagnostic image representations of an object when the object is positioned within the examination region, and a patient support adapted for movement through the examination region. The method includes moving a flat panel image detector that is mechanically coupled to the frame from a stored position remote from the patient support to an operating position proximate the patient support, the radiation detector panel detecting x-rays generated by an x-ray source and generating signals indicative of the radiation detected, and reconstructing the fluoroscopic projection image representations from the signals generated by the radiation detector panel.
- In accordance with a further aspect of the present invention, a fluoroscopy imaging device which generates at least one of a fluoroscopic image representation and a radiographic image representation of an object is disclosed. The fluoroscopy imaging device includes a mobile cart, an x-ray source for transmitting x-rays, a flat panel image receptor for detecting the x-rays and generating signals indicative of the detected x-rays, and a support member secured to the mobile cart for supporting the x-ray source and the flat panel image receptor.
- One advantage of the present invention is the provision of a fluoro-assist device for a CT scanner which is readily available when needed.
- Another advantage of the present invention is the provision of a fluoro-assist device for a CT scanner which permits real-time imaging of minimally invasive tools (catheters, needles, etc.) that are inserted in a CT suite.
- Yet another advantage of the present invention is the provision of a fluoro-assist device for a CT scanner where a interventionalist can work behind a flat panel image receptor which acts as a primary barrier to radiation exposure.
- Still another advantage of the present invention is the provision of a fluoro-assist device for a CT scanner which incorporates a flat panel image detector.
- Still further advantages of the present invention will become apparent to those of ordinary skill in the art upon reading and understanding the following detailed description of the preferred embodiments.

- With reference to FIGS. 1 and 2, an exemplary
diagnostic imaging system 2, such as aCT scanner 4, includes a floor-mounted, non-rotating frame member or gantry A whose position remains fixed during data collection. An x-ray tube B is rotatably mounted on a rotating frame member or gantry C. The stationary gantry A includes acylinder 10 that defines apatient examination region 12. An array ofradiation detectors 14 are disposed concentrically around the patient receiving region. In the illustrated embodiment, the x-ray detectors are mounted on the stationary gantry portion such that an arc segment of the detectors receives radiation from the x-ray tube B which has traversed theexamination region 12. Alternatively, an arc segment of radiation detectors can be mounted to the rotating gantry to rotate with the x-ray tube. The x-ray tube B andradiation detectors 14 comprise a diagnostic imaging subsystem of the diagnostic scanner. - A
control console 16 contains animage reconstruction processor 18 for reconstructing an image representation out of signals from thedetector array 14. Preferably, the image reconstruction processor reconstructs a volumetric image representation from radiation attenuation data taken along a spiral path through the patient. A video monitor 20 converts selectable portions of the reconstructed volumetric image representation into a two-dimensional human-readable display. Theconsole 16 includes tape and disk recording devices for archiving image representations, and also includes circuitry for performing image enhancements, selecting planes, 3D renderings, or color enhancements, and the like. Various scanner control functions such as initiating a scan, selecting among different types of scans, calibrating the system, and the like, are also performed at thecontrol console 16. - The x-ray tube B includes an oil filled housing that has an x-ray permeable window directed toward the patient receiving region. An evacuated envelope is disposed within the housing and contains a rotating anode, such as a 7-inch anode, and a cathode or other electron source. High voltages, on the order of 150 kV applied between the rotating anode and the cathode, cause the generation of x-rays. The x-rays pass through the x-ray permeable window and across the
patient receiving region 12. -
Appropriate x-ray collimators 22 focus the radiation into one or more planar beams which span theexamination region 12, as is conventional in the art. Theconsole 16 includes circuitry for gating the x-ray source B to control patient dosage. A high voltage power supply is mounted on the rotating gantry for rotation with the x-ray tube. - A fixed patient table24 is positioned adjacent the diagnostic scanner so as to extend from the
examination region 12 in a first direction substantially along a central axis of thecylinder 10. Apatient beam 26 is secured to an upper surface of the patient table 24. Apatient couch 28 is slidably secured to thepatient beam 26 for back and forth movement through theexamination region 12 along thebeam 26. It should be appreciated that at least the patient couch can be configured to pan laterally relative to a longitudinal axis of the gantry bore. The table 24,beam 26, andcouch 28, cooperate to define a patient support which is adapted for movement through the examination region. - An integrated fluoroscopy or fluoro-assist device D is secured to the gantry A for movement between an operating position (FIG. 1) and a stored position (FIG. 2). The fluoro-assist device includes a support member that is movably secured to either side of the gantry A via a mounting structure E. In the embodiment being described, the support member is a C-
arm 30. - A fluoroscopic x-ray source or
tube 32 is secured proximate a first end of the C-arm 30 via a cantileveredsupport bracket 34. Likewise, an opposingx-ray detector 36 is secured proximate a second end of the C-arm 30 via a cantileveredsupport bracket 38. Anupper counterweight 39 a extends from the first end of the C-arm and alower counterweight 39 b extends from the second end of the C-arm. Thex-ray source 32 anddetector 36 cooperate to define a fluoroscopic imaging subsystem of the diagnostic scanner. - In the embodiment being described, the mounting structure E includes a first link or
support arm 40 having one end pivotally secured to the gantry A and the other end pivotally secured to a second link orsupport arm 42. A firstupright support arm 44 is movably secured to thesecond arm 42 for substantial horizontal movement along atrack 46 associated with thesecond arm 42. A secondupright support arm 48 is movably secured to the firstupright support arm 44 for substantial vertical movement along a common longitudinal axis of theupright support arms arm 30 is rotatably supported by a bearingassembly 50 associated with the secondupright support arm 48 which permits thex-ray source 32 anddetector 36 to rotate about a geometric center of the C-arm through an arc of at least 180°. - The mounting structure E permits the C-arm to be conveniently stored or parked along the side of the gantry when not in use, and, when needed, to be positioned in front of the gantry with the
x-ray source 32 placed directly under the patient table. In particular, thefirst support arm 40 pivots approximately 180° around the gantry when moving the C-arm between the stored position and the operating position. Further, thesecond support arm 42 pivots approximately 90° around thefirst support arm 40 when moving the C-arm between the stored position and the operating position. However, it should be appreciated that the C-arm can be mounted to any other part of the gantry. - The bearing
assembly 50 permits the C-arm 30, and thus thex-ray source 32 anddetector 36, to be rotated around a longitudinal axis of the patient from the “under table” position shown in FIG. 1, to a lateral position on either side of the patient table. This provides a ±90°, or any angle in-between, movement of thex-ray source 32 anddetector 36 from the “under table” position to provide lateral imaging from both sides of the patient. - The C-
arm 30 moves vertically as the secondupright support arm 48 telescopically extends and retracts vis-a-vis the firstupright support arm 44 to permit easier access to the patient and to adjust image magnification. The C-arm also moves laterally across the patient with the first and secondupright support arms track 46 to allow lateral image panning across a patient's body. Longitudinal image panning (i.e. along a patient's body) is accomplished by automatically or manually driving thepatient couch 28 in either or both directions along therail 26. It should be appreciated that the bearingassembly 50 could permit the plane of the C-arm to rotate or tilt from an orientation normal to an axis of the patient support (e.g. to a position with thex-ray source 32 over the patient table and thedetector 36 under the patient table). Thus, an operating position of the flat panel image detector is broadly defined herein as any position or orientation (i.e. above, below, adjacent, etc.) of thedetector 36 relative to the patient support without regard to the position of the detector relative to the gantry bore (i.e., within the bore or proximate the bore). The stored position of thedetector 36 is defined as a position which is remote from at least one of the patient support and the gantry bore. - Referring now to FIG. 3, the
x-ray source 32 and thedetector 36, and more particularly acenterline 51 of the imaging system, is offset a distance F from a plane of the C-arm by the cantileveredsupport brackets centerline 51. By offsetting the x-ray source and detector offset from the C-arm, interference caused by the C-arm during interventional procedures is minimized. - The
centerline 51 of the imaging system intersects with the orbit axis G of the C-arm. As a result, both the geometric center of the C-arm 30 and theimaging system centerline 51 are positioned at iso-center during a fluoroscopic imaging procedure. Theimaging system centerline 51 rotates around, but does not shift laterally relative to, iso-center when the C-arm is orbited. - In contrast, with known C-arm systems, the centerline of the imaging system is laterally offset from the orbit axis of the C-arm. During an imaging procedure, the centerline of the imaging system is positioned at iso-center and the orbit axis of the known C-arm is laterally offset from iso-center. When the known C-arm is rotated about its orbit axis, the imaging system centerline shifts off iso-center. Thus, in order to maintain the imaging system centerline at iso-center when a known C-arm system is orbited, the whole C-arm must be laterally repositioned in addition to being orbited.
- Referring now to FIGS. 4 and 5, a cable take-up/tension control system F for the C-
arm 30 is shown. It should be appreciated that the C-arm is shown with one or more protective covers removed. One or more data/power cables 52 connect thex-ray source 32 anddetector 36 to a fluoro-image reconstruction computer 54 andpower supply 56 housed in acabinet 58 which is mounted to the side of the gantry. Afirst hose anchor 60 secures an intermediate portion of thecable 52 to thecabinet 58. Asecond hose anchor 62 secures another intermediate portion of the cable to the upper end of the C-arm. Acable guide 64 is positioned on or above the secondupright support arm 48 proximate the bearingassembly 50. The cable guide includes an aperture through which thecable 52 slidably passes. The portion of thecable 52 extending between thecable guide 64 and thefirst anchor 60 forms a variablelength service loop 66. A portion of thecable 52 extending between thecable guide 64 and thesecond anchor 62 rests at least partially within anopen channel 68 defined within an exterior surface of the C-arm. When the C-arm is rotated in a clockwise direction from the upright position shown in FIG. 4, a portion of thecable 52 resting within thechannel 68 passes through thecable guide 64 and is taken up by theservice loop 66. Likewise, when the C-arm is rotated in a counter-clockwise direction, a portion of thecable 52 defining theservice loop 66 passes through thecable guide 64 and is guided into thechannel 68. - A portion of the
cable 52 extending past thesecond anchor 62 wraps around theupper counterweight 39 a and passes through one or moreclosed channels 70 forming an inner portion of the C-arm 30. A portion of thecable 52 within the C-arm channels 70 pass through thesupport arms x-ray source 32 anddetector 36, respectively. - Referring now to FIG. 6, the
detector 36 includes ahousing 72 which supports a flat panel image receptor or array 74 (shown in phantom) of individual image receptors. A “flat panel image receptor” as used herein includes a planar substrate such as glass laminated with an array of sensors such as amorphous silicon crystals that convert x-ray energy to electrical signals. That is, the sensors emit an electronic potential when struck by photons of x-ray energy. The intensity of the potential is related to the intensity of the x-ray beam. The electrical signals can be read out from a row/column matrix and then converted to digital data. - In the embodiment being described, an amorphous silicon flat panel image receptor includes a Cesium Iodide scintillating layer on an amorphous silicon glass substrate. The scintillating layer converts x-ray energy into light. An array of photodiodes on the glass substrate convert the light into electrical signals. The electrical signals are readout of a row/column matrix that is accessed using thin film transistor switches on the amorphous silicon substrate. The analog data is then converted to a digital format.
- The amorphous silicon flat panel image receptor is compact in size and weight and replaces the conventional image intensifier tube, thus reducing the size of the
detector 36. The mechanical support (i.e. support arm 38) for thedetector 36 is also reduced in size and weight. Further, the flat panel image receptor 74 provides a rectangular image, eliminates the distortion of an image common to conventional image intensifier tubes, and provides constant image quality across the flat panel of the image receptor, thus minimizing the amount of panning typically required with conventional image intensifier tubes. It should be appreciated that the flat panel image receptor can be of any dimension such as 20 cm×25 cm, and the system can be easily upgraded to incorporate larger flat panel image receptors. It is contemplated that a fluoro-assist device having a conventional image intensifier or alternate technology can be mechanically coupled to an imaging system in the same or similar manner as described above. - The
housing 72 includes two handles integrally formed therein. Afirst control panel 76 a is mounted at one end of thehousing 72 adjacent one handle, and asecond control panel 76 b is mounted on the opposite end of the housing adjacent the other handle. Depending upon the particular orientation of the C-arm, eithercontrol panel - When the C-
arm 30, and thus thex-ray source 32 anddetector 36, is rotated to a lateral position on either side of the patient table, a physician performing an interventional procedure may position himself/herself behind the offsetdetector housing 72 to prevent direct exposure to the x-ray beam generated by thesource 32, and to reduce exposure due to scattered radiation. The flat panel image receptor 74 may incorporate a lead shielding layer or other radiation absorbing material therein to minimize radiation exposure to the medical personnel. Alternatively, a lead shield may be incorporated into thehousing 72. - As described above, the flat panel image receptor74 within the
housing 72 is coupled to the fluoro-image processing computer 54 housed in thecabinet 58 mounted to the side of the gantry. The fluoro-image processing computer 54 processes the acquired image from thedetector 36 and permits an operator to adjust window and level functions of the displayed image. The fluoro-image generated by the fluoro-image reconstruction computer is displayed on an adjustable monitor 78 (FIGS. 1 and 2) connected to the gantry via alateral support arm 80. Alternatively, themonitor 78 can be suspended from the ceiling, or located on a cart. Themonitor 78 can be either a flat panel monitor or a standard CRT monitor. In addition, the fluoro-image output could go directly to a filming device. The fluoro-image output could also go to the diagnostic system and be displayed with the volumetric images on thedisplay 20. - The fluoro-assist device D may be activated and deactivated with a foot pedal82 (FIG. 1) in a conventional manner. When activated, the fluoro exposure can be either continuous or pulsed. In the pulsed mode, radiography procedures can be performed, such as CINE, Spot Film and DSA, thereby generating radiographic image representations. The
x-ray source 32 can be gated on and off in the pulsed mode using a conventional grid control circuitry or a pulse fluoro high-voltage power supply. - Referring now to FIGS.7-9, the C-arm can be a stand-alone device which is mounted near the gantry and which provides the same functions described above. In particular, a C-
arm 90 is suspended from a ceiling via a mounting structure such as an overhead track system G includingfirst rails 92, andtransverse rails 94 which are movable along the first rails 92. Atrolley 96 is movably secured to thetransverse rails 94 in directions transverse to therails 92. Atelescopic support arm 98 extends from thetrolley 96. Acantilevered beam 100 extends from thetelescopic arm 98 to support the C-arm 90. To reduce the torque applied to thebeam 100, the C-arm is secured to an upwardlyangled end portion 102 of thebeam 100 which reduces the separation between the C-arm and thetelescopic arm 98. - A fluoroscopic x-ray source or
tube 104 is secured to an upper free end of the C-arm 90, and an opposingx-ray detector 106 is secured to the lower free end of the C-arm 90. As stated above, thex-ray source 104 can include a fixed or rotating anode x-ray tube with an integral or separate high voltage supply, and thedetector 106 includes an amorphous silicon flat panel image receptor orarray 108. - As shown in FIG. 8, the overhead track system G is oriented above the diagnostic scanner so that the C-
arm 90 may be positioned in a stored position remote from the gantry, and positioned in an operating position between the patient table 24 and the front of the gantry A. In particular, the C-arm 90 may be positioned with thedetector 106 substantially adjacent thepatient rail 26 so that thepatient couch 28 may be driven between thex-ray source 104 and thedetector 106. Alternatively, as shown in FIG. 5, the C-arm 90 may be positioned in an operating position adjacent the rear of the gantry A so that thepatient couch 28 must be driven through the bore of the gantry before passing between thex-ray source 104 and thedetector 106. - Referring now to FIGS.10-12, a support member such as a
ring 110 is suspended from a mounting structure such as an overhead track system H which includesparallel rails 112 and atrolley 114 movably secured to therails 112. Asupport arm 116 is suspended from thetrolley 114. Thesupport ring 110 is secured to a cantilevered lower portion of thesupport arm 116. Thesupport ring 110 defines a tapered, annular side wall having a first diameter at anend edge 118, and a second diameter greater than the first diameter, at anopposing end edge 120. - A fluoroscopic x-ray source or
tube 122 is secured to an upper portion of thesupport ring 110 adjacent theend edge 120. Anangled support 124 is secured to a lower portion of thesupport ring 110 adjacent theend edge 120. An amorphous siliconflat panel detector 126 is secured to a planar surface of thesupport 124 substantially beneath thex-ray source 122. - The overhead track system H is oriented above the diagnostic scanner so that the
support ring 110 can be positioned in a stored position remote from the gantry and in an operating position at least partially within the bore of the gantry A. In particular, the tapered annular sidewall defining thesupport ring 110 conforms to the mutually tapered sidewall defining the bore of the gantry to facilitate accurately and repeatably positioning thex-ray source 122 and thedetector 126 relative to thepatient couch 28 which is driven through the bore. Thus, with the support ring positioned in the bore, thepatient couch 28 may be driven through the gantry and between thex-ray source 122 and thedetector 126 which are positioned immediately adjacent the rear of the gantry. - Referring now to FIGS. 13 and 14, an
alternate support ring 130 is suspended from the previously described overhead track system H for movement between a stored position remote from the gantry and an operating position.
