Description
Technical field
The present invention relates to a kind ofly, and regulate the wireless capsule endoscopic system and the method for capture rate through existing image recognition technology detecting suspected lesion zone.
Background technology
The human history of using endoscope to detect intracorporeal organ can trace back to for 19th century, and Germany scientist Philipp Bozzini had invented endoscope's blank of using candle light detecting human bladder and intestinal first in 1806.After this, different types of endoscope is (like gastroscope, in order to the detecting Gastric Diseases by Spraying; Colonoscope is in order to detect the intestinal pathological changes) by development constantly and improvement, the disease that patient carries out the live body digestive system is detected in order to help the doctor.
In more than ten years in the past; The science and technology that endoscope is relevant has obtained development rapidly; Particularly a kind of medical science auxiliary facilities that can be used to remedy and promote gastroscope and colonoscope---the birth of wireless capsule endoscope makes and detects stomach and enteric disorders simultaneously and possibly become.The method for using that is different from conventional endoscope, when using capsule endoscope, the doctor need not the scope of band flexible pipe is filled in the patient body.When examining, the patient can keep normal activity and life.Because capsule endoscope can supply the people to swallow, it has smaller volume, has therefore largely reduced the misery that conventional endoscope (with soft pipeline) is brought to patient; And convenient and healthy, obtained the approval of medical circle.Simultaneously, conventional endoscope such as gastroscope and colonoscope cause it can go deep into being limited in scope of human body observation because of the restriction of hose length and bendable curvature, and the pathological changes that is applied as observation human small intestine section of wireless capsule endoscope provides probability.
Wireless capsule endoscope is a kind of miniature electric armarium of capsule appearance, built-in the LED of light source, the imaging system that is used to catch image, multiple sensors is provided, is used to provide battery, transmitter module and the antenna elements such as (transmission and processing signals) of the power supply of each module.The wireless capsule endoscope that has been employed at present; As by the M2A type capsule endoscope of Olympus pharmaceuticals research and development (be of a size of 11mm * 27mm), after being swallowed by human body, but continuous operation 7～8 hours; Therebetween; Can take pictures to digestive system with the speed of per second two frames, finally obtain about 50,000 colour pictures.Capsule shell is by special biomaterial sealing, can resist gastric acid and powerful digestive enzyme.After being swallowed by patient, capsule endoscope can by the traction of peristalsis of the digest tract or positioning control system slowly propelling or stop at the aura position, for the full section of small intestinal that reaches 5-7 rice provides effective inspection means.
Yet the retrievable picture quality of capsule is limited at present, makes traditional capsule image taking and processing mode not reach optimal effect, has the probability of mistaken diagnosis.And because capsular moving depends on Alimentary wriggling; Its instant movement rate since between Different Organs environmental differences and Different Individual the difference of digestion power etc. have nothing in common with each other; Make based on the diagnosis rate of the capsule system of existing image processing method and image taking speed also imperfectly, promptly when the capsule movement rate is very fast, have certain possibility of failing to pinpoint a disease in diagnosis.In February, 2011; " point out that using the diagnosis success rate of wireless capsule endoscope separately is 81.73% in " capsule endoscope, two air bag scope separately with unite the health economics that utilization renders a service diagnosis of small bowel diseases comment " that Chinese scope journal is delivered, only just can make diagnosis rate reach 90.56% when using simultaneously with two air bag scopes (still for being positioned over the traditional endoscope in the long pipeline).
Using more, the image processing method of intelligence is a good method of improving diagnosis rate.Given Imaging Ltd. had once issued one piece about in wireless capsule endoscope, using the technology of captured image and existing database images characteristic matching and the patent that is numbered JP2007105458 of method (delivering simultaneously to being numbered the patent of EP1770570 and AU2006220372) in April, 2007.This technology transfers to device outside through the picture that wireless capsule endoscope is photographed and the characteristics of lesion image in the data base in these photos and the extracorporeal treatment system is compared and mate, demonstrate again with the data base in the shooting results that coincide of disease characteristic.Increased the sensitivity of system thus, made things convenient for doctor's detection, and shortened detection time the suspected lesion zone.Yet this kind method still has because of capsule comparatively fast causes a limited number of situation of under the situation that does not change the speed of taking pictures, taking pictures in the lesion region translational speed, still has bigger omission probability thus.
It also is to improve the most effectively way that is detected as power that the more images data are provided.But capsule self energy storage is limited, how need not significantly to increase under the situation of capsular energy consumption, and regulating image taking speed effectively and targetedly becomes one of key factor of decision capsule efficient.The characteristics that capsule rate travel when the Chinese patent of announcing in March, 2010 that is numbered CN101674769 once proposed according to capsule endoscope Different Organs of living in has nothing in common with each other; Infer that capsule moves to the time required in the Different Organs; Again by timer confirm after the swallowable capsule through duration, be controlled at via built-in chip and regulate the capsular speed of taking pictures after reaching specific preset time.This method avoided some digestive organs endogenous cause of ill capsule move too fast (stomach bigger, capsule possibly vertically drop) like the space thus and the probability of the limited inconvenient diagnosis state of an illness of the amount of taking pictures that causes.But this kind method does not change capture rate based on the suspected lesion zone targetedly; Be that the photo amount of effective lesion region and the photo amount of normal areas are as good as; Insignificant information accounts for the large percentage of gross information content; Handle and screening has increased burden for later image, also be not easy to doctor's observation and diagnosis.
This shows; Existing wireless capsule endoscope still exists because of picture quality Flame Image Process mode, capture rate; The undesirable flase drop that causes of factors such as photographic intelligence amount and the probability of omission are fast and effeciently to help the doctor to detect a big obstacle of patient's state of an illness.Based on the defective and the prior art background of above wireless capsule endoscope, the present invention proposes through image recognition technology and confirm the suspected lesion zone and promote the novel radio capsule endoscope system and the method for capsule photographic images speed in this type of zone.
