Abstract
The invention relates to a process for calibration of a medical-technical device which is in operation as a result of mounting a new component on the medical-technical device. The invention moreover relates to a medical-technical device which is made such that it automatically identifies the new component when a new component is mounted on the medical-technical device and displays the necessary steps for calibration of the medical-technical device based on the identification. The medical-technical device however can also be made such that it automatically identifies the newly attached component after its identification.
Description
- This application is a division of co-pending application Ser. No. 10/246,655, filed on Sep. 19, 2002, the entire contents of which are hereby incorporated by reference.
- The invention relates to a process for calibration of a medical-technical device which is in operation as a result of mounting a new component on the medical-technical device. The invention moreover relates to a medical-technical device which is made such that it automatically identifies the new component when the latter is mounted on the medical-technical device.
- If in a medical-technical device which is in operation a replacement part or an additional component is installed or connected, a service technician who is installing or connecting the replacement part or the additional component must generally recalibrate the medical-technical device. The concept of “calibration” is understood in its widest sense in connection with this application. Calibration is defined among others as the adjustment of the medical-technical device including the new component, or when the new component is for example a software update, configuration of the computer which comprises the medical-technical device. The service technician during calibration can consult suitable manuals which include instructions for calibration of the medical-technical device.
- Based on legal regulations the manufacturer of the medical-technical device when the replacement part or additional component is installed must keep a record of the installed replacement part or the installed additional component and about the corresponding medical-technical device. Therefore the service technician after completion of the installation notates the identification number assigned to the installed replacement part or the installed additional component, for example a material number, a serial number, or an inspection number of the replacement part or the additional component, and communicates this to the central administrative department of the manufacturer. In the administrative department these identification numbers are entered in a suitable database or card file.
- The object of the invention is therefore to devise a process and a medical-technical device such that there is the prerequisite for easier calibration of the medical-technical device on which the new component is located.
- The first object of the invention is achieved by a process for calibration of a medical-technical device which is in operation as a result of the attachment of a new component to the medical-technical device, having the following process steps:
- automatic identification of the new component by the medical-technical device and based on the identification of the new component, display of the steps necessary for calibration of the medical-technical device by the latter.
- The first object of the invention is also achieved by a process for calibration of a medical-technical device which is in operation as a result of mounting a new component on the medical-technical device, having the following process steps:
- automatic identification of the new component by the medical-technical device and based on the identification of the new component, automatic calibration of the medical-technical device.
- Therefore a new component is mounted on the medical-technical device which is in operation, therefore which has already been installed and is being used properly. The new component replaces, for example, according to versions of the invention, a component of the medical-technical device or is mounted additionally on the medical-technical device. The new component is thus especially a replacement part or retrofit of the medical-technical device. As a result of the mounting of the new component on the medical-technical device, which can be for example installation or connection of the new component or reading in new software into the computer which has the medical-technical device, the medical-technical device must generally be recalibrated. The concept “calibration of the medical-technical device” should otherwise be understood in the widest sense. It comprises especially necessary adjustments on the medical-technical device or the newly mounted component and also configuration of the computer so that the medical-technical device is ready again for operation in the proper manner with the newly mounted component.
- As claimed in the invention the medical-technical device automatically identifies the new component which has been newly mounted on the medical-technical device. Then, the medical-technical device for example with a monitor of the medical-technical device displays the individual steps which are necessary for the calibration of the medical-technical device and which then are carried out by the service technician who has mounted the new component on the medical-technical device. Thus the service technician does not need to consult the manual for calibration. But all necessary steps for calibration of the medical-technical device are displayed to him. Therefore he is guided by the medical-technical device through the individual steps of calibration which are to be carried out.
- Instead of displayed steps, the medical-technical device can also be automatically calibrated. Based on the identification of the new component, for example a computer program stored in the computer of the medical-technical device can be automatically retrieved, which thereupon automatically executes the steps necessary for calibration of the medical-technical device. These steps can be among others automatically taken measurements. Consequently the service technician must simply mount the new component on the medical-technical device. The necessary measures for calibration of the medical-technical device are then either carried out automatically or the steps which the service technician is to carry out are displayed. Thus the medical-technical device can be quickly, reliably and easily transferred again into a serviceable state as a result of installation of an additional component or based on replacement of a component. Calibration is consequently facilitated, by which expensive work time can be saved.
- According to one especially preferred embodiment of the invention, it is provided that the new component has a part which comprises a data record suitable for identification of the new component. This data record according to versions of the invention comprises a serial number, an inspection number and/or a material number and/or at least one important characteristic of the new component. This data record is read out according to one especially preferred version of the invention by the computer of the medical-technical device so that the medical-technical device identifies the new component. A part which is suitable for the purposes of the process as claimed in the invention is described for example in U.S. Pat. No. 5,994,770, reference to the disclosure contents of which is hereby made. The part of U.S. Pat. No. 5,994,770 is a part for storage of data for identifying products. This part can be read out electronically.
- According to another version of the invention, it is provided that after identification of the new component the medical-technical device sends a message to a central data processing system, the message comprising an entry about the medical-technical device and the new component. As stated in the introduction, manufacturers of medical-technical devices are legally mandated to keep a record of installed or supplied components of the medical-technical device. As claimed in the invention therefore the medical-technical device, after it has identified the new component, generates the message and sends it to the central data processing system. The central data processing system can be located for example in the headquarters of the manufacturer. Based on the message sent to the central data processing system it is possible for the manufacturer to easily acquire delivered and/or installed components of medical-technical devices and to keep the legally mandated record. The manufacturer is thus able to easily keep information about the location of components of medical-technical devices manufactured, installed or delivered by him.
- According to one embodiment of the invention, the message comprises an entry about the serial number, material number and/or an inspection number of the new component.
- If according to one especially preferred embodiment of the invention the message is generated after calibration of the medical-technical device and is sent to the central data processing system and if it comprises the data generated during calibration, proper installation of the new component can be easily monitored and recorded.
- According to one version of the invention the message is transmitted via a long-distance data transmission means, as for example the telephone network or the Internet, to the central data processing system.
- According to one version, the medical-technical device is a magnetic resonance device, a computer tomograph, an x-ray device, a lithotripter, an ultrasonic device, an isotope scanner or a device for radiation therapy. An isotope scanner is used otherwise especially in nuclear medicine.
- The second object of the invention is achieved by a medical-technical device which is made such that it automatically identifies the new component when the latter is mounted on the medical-technical device and displays the necessary steps for calibration of the medical-technical device based on the identification.
- The second object of the invention is likewise achieved by a medical-technical device which is made such that it automatically identifies the new component when the latter is mounted on the medical-technical device and automatically carries out calibration based on the identification.
- Mounting of a new component which according to embodiments of the invention replaces a component of the medical-technical device or is mounted additionally on the medical-technical device, is for example the installation or connection of the new component. Mounting can also be however copying of a software update onto a computer which comprises the medical-technical device. After mounting the new component, the medical-technical device as claimed in the invention automatically recognizes the new component and thereupon for example on a display of the medical-technical device displays the necessary steps for calibration of the medical-technical device. The calibration steps can then be carried out by the service technician. Alternatively the medical-technical device, after it has identified the new component, can be automatically calibrated. Calibration in this connection means especially resetting the medical-technical device with the newly mounted component, which resetting is necessary due to the mounting of the new component. If it is a software update, calibration of the medical-technical device in particular is reconfiguration of the computer of the medical-technical device which may have become necessary.
- Advantageous embodiments of the invention result from the dependent claims. Thus, according to one embodiment of the invention, among others it is provided that the new component has a part which comprises a data record which is suitable for identification of the new component. In this component, as is described for example in U.S. Pat. No. 5,994,770, according to one embodiment of the invention a serial number, an inspection number and/or a material number of the new component can be stored. The data record of the part can also comprise an entry about at least one important characteristic of the new component, according to another version of the invention.
- Consequently it is possible for the medical-technical device to identify the new component by its reading out the data record of the part of the new component with the computer of the medical-technical device, as is provided especially according to one version of the invention.
- As already described in the introduction, manufacturers of medical-technical devices are obligated to keep a record of installed replacement parts and new components. In one especially advantageous embodiment of the invention it is therefore provided that the medical-technical device after identification of the new component generates a message and sends it to a central data processing system, the message comprising an entry about the medical-technical device and the new component. In the central data processing system, based on the message for example it is easily possible to store in a database where and in which medical-technical device the new component, for example, the replacement part or the newly mounted component, is installed. Manual detection of the newly mounted part is thus eliminated, by which reliable detection of the newly arranged component is greatly simplified.
- The message can comprise especially according to one version of the invention an entry about a serial number, a material number and/or an inspection number of the new component.
- If according to one especially preferred version of the invention, during calibration the data assigned to calibration are generated and these data are transmitted at least as part of the message to the central data processing system after completion of calibration, in the central data processing system a record can be additionally kept about the correct arrangement of the new component. Moreover, it is easily possible to centrally monitor whether the medical-technical device has been properly calibrated.
- According to another version of the invention, the message is sent via a long-distance data transmission means to the central data processing system. The long-distance data transmission means is for example the Internet, ISDN (Integrated Services Digital Network) or a suitable telephone network.
- According to another version of the invention the medical-technical device is a magnetic resonance device, a computer tomograph, an x-ray device, an lithotripter, an ultrasonic device, an isotope scanner or a device for radiation therapy. If for example the medical-technical device as claimed in the invention is a magnetic resonance device and a customer as an option buys an additional head coil for the magnetic resonance device, the head coil is delivered to the customer and then installed in the magnetic resonance device by the service technician. After installing the head coil the magnetic resonance device automatically recognizes the serial number, the inspection number and the material number of the head coil and acquires them. Then the magnetic resonance device automatically initiates the corresponding electrical calibration and in doing so prepares calibration tables, for example. In the course of this electrical calibration, individual steps to be carried out by the service technician can be displayed on the display of the magnetic resonance device. The electrical calibration can however also be carried out independently by the magnetic resonance device. Within a very short time the customer can use the new head coil. Moreover, the data electronically acquired by the magnetic resonance device can be remotely transmitted to the headquarters of the manufacturer of the magnetic resonance device. In the main headquarters is the central data processing system in which the electronically acquired data are stored in a special database. With the data stored in the database thus a record of the delivered and installed option, i.e. the aforementioned head coil, is easily possible.
- One embodiment of the invention is shown by way of example in the schematics.
-
FIG. 1 shows a computer tomograph, -
FIG. 2 shows an x-ray tube and -
FIG. 3 shows a flowchart. -
FIG. 1 shows by way of example and schematically a side view of acomputer tomograph 1 with an annularly madegantry 2 which is supported on thestationary housing 3 of thecomputer tomograph 1 to be able to turn in the direction of the arrow a around an axis ofrotation 4 aligned at a right angle to the axis of the paper ofFIG. 1 . Thehousing 3 of thecomputer tomograph 1 in the case of this embodiment is not detailed. - On the
gantry 2 there are several components which in the case of this embodiment comprise anx-ray source 5, aradiation detector 6 opposite thex-ray source 5, and a cooling means 7 which is not detailed for dissipating the heat which is produced by the x-ray tube of thex-ray source 5 in operation of thecomputer tomograph 1. In operation of thecomputer tomograph 1 thegantry 2 rotates around theaxis 4 of rotation, a fan-shaped x-ray beam emerging from thex-ray source 5 penetrating themeasurement field 9 at different projection angles and striking theradiation detector 6. From the output signals of theradiation detector 6 which arise adata acquisition device 10 forms the measured values which are sent to thecontrol computer 11 of thecomputer tomograph 1. Thecontrol computer 11 computes therefrom a picture of the patient who is in themeasurement field 9 and who is not shown inFIG. 1 . In the case of this embodiment thedata acquisition device 10 is connected to thecontrol computer 11 with anelectrical line 12 which contains for example a slip ring system or a wireless transmission section in a manner which is not shown. The electrical connections of thex-ray source 5 and of theradiation detector 6 are accomplished in a conventional manner which is not shown. The picture computed by thecontrol computer 11 can then be viewed with themonitor 18 which is connected to thecontrol computer 11 with anelectrical line 19. - In the case of this embodiment, the x-ray tube of the
x-ray device 5 is defective. It was therefore replaced by aservice technician 14 with thex-ray tube 20 shown inFIG. 2 . Thex-ray tube 20 in the case of this embodiment comprises anelectronic part 21 which is mounted on thex-ray tube 20. Thepart 21 stores a data record which in the case of this embodiment comprises the serial, material and inspection numbers of thex-ray tube 20. An electrical voltage necessary for operation of thepart 21 takes place via anelectrical line 13 which in a manner not shown comprises a slip ring system and with which thepart 21 after installation of thex-ray tube 20 in thecomputer tomograph 1 is connected to thecontrol computer 11 of the computer tomograph. One embodiment of thecomponent 21 is otherwise described in U.S. Pat. No. 5,994,770, the disclosure contents of which are hereby included (step A of the flow chart shown inFIG. 3 ). - In the case of this embodiment, data are also transmitted from the
part 21 via theelectrical line 13 to thecontrol computer 11 so that after connection of the x-ray tube 20 a computer program stored in thecontrol computer 11 reads out the data record stored in thepart 21. As a result of reading out of the data record the computer program stored in thecontrol computer 11 automatically identifies the newly mounted x-ray tube 20 (step B of the flow chart shown inFIG. 3 ). - Based on the identification of the newly mounted
x-ray tube 20 on thecomputer tomograph 1 the computer program stored in thecontrol computer 1 begins to automatically reset thecomputer tomograph 1 with the newly connectedx-ray tube 20. During the automatic adjustment it is necessary among others for theservice technician 14 to carry out individual steps for making the adjustments. The computer program stored in thecontrol computer 11 is therefore executed such that it displays these necessary steps to theservice technician 14 on themonitor 18. One example of this step is triggering of the x-radiation of the x-ray tube for test purposes (step C of the flow chart shown inFIG. 3 ). - During adjustment of the
computer tomograph 1, the computer program stored in thecontrol computer 11 generates another data record that checks whether thecomputer tomograph 1 has been properly set so that it can be used properly again. The further data record likewise comprises an entry about the serial number, the material number, and the inspection number of thex-ray tube 20 and an entry for identification of thecomputer tomograph 1. This data record is stored in the case of this embodiment in adatabase 11 a of thecontrol computer 11. - In the case of this embodiment, the
control computer 11 of thecomputer tomograph 1 is moreover connected to thepublic telephone network 15 so that it can transmit data to thedata processing system 17 which is likewise connected to thepublic telephone network 15. Thedata processing system 17 is located in the case of this embodiment in anoffice 16 of the manufacturer of thecomputer tomograph 1. - After the
computer tomograph 1 has been adjusted, thecontrol computer 11 automatically transmits the other data record generated during adjustment of thecomputer tomograph 1 to thedata processing system 17. Thedata processing system 17 furthermore comprises adatabase 17 a in which this other data record is stored. Since the other data record comprises information suitable for identification of thex-ray tube 20 and for identification of thecomputer tomograph 1, it can be used for the legally mandated record of the location of the installed x-ray tube 20 (step D of the flow chart shown inFIG. 3 ). - In the case of this embodiment the installation of a replacement part in the form of the
x-ray tube 20 in thecomputer tomograph 1 is described. Other components of thecomputer tomograph 1, such as for example thegantry 2, theradiation detector 6, the cooling means 7, thedata acquisition device 10, thecontrol computer 11, etc. can likewise be replaced by a suitable replacement part. - But it is also possible for the additional component, for example a laser light sight, to be connected to the
computer tomograph 1. Here a new component can also be a software update and the adjustment of thecomputer tomograph 1 can be reconfiguration of thecontrol computer 11 which is necessary because of a software update. - The process as claimed in the invention can also be used for another medical-technical device, such as for example for a magnetic resonance device, a lithotripter, an ultrasonic device, an x-ray device, an isotope scanner or a device for radiation therapy. A medical-technical device as claimed in the invention need not necessarily be a computer tomograph.
- The described embodiment is otherwise only of an exemplary nature.
