Capsule endoscopy auxiliary film reading method

Abstract

The invention discloses a capsule endoscopy auxiliary film reading method, belonging to the biological image recognition technology field and comprising: downloading the image shoot by the capsule endoscopy to the image film reading workstation, before film reading, preprocessing the images by an auxiliary film reading system; in detail, firstly, training a focus site categorizer for preparing to recognize the focus site; secondly, applying the pattern recognition technology to delete the redundant frames with high similarity in the endoscopy image sequence, only retaining the image frame including most information, compressing the endoscope image sequence; finally, matching the compressed image sequence and the focus site categorizer based on the trained focus site categorizer, labeling the focus site therein. The auxiliary film reading system comprises a categorizer train module, a similar frame detection module and a focus characteristic analysis module. The categorizer train module finishes the train of the normal capsule endoscopy image characteristic categorizer and the focus site capsules endoscope image categorizer. The similar frame detection module finishes the image detection with high similarity, removes some redundant image. The focus characteristic analysis module judges whether the focus site is in the image and labels if there is.

Description

Technical field: [0001] The invention belongs to the technical field of biological image recognition, which reduces the number of photos and finds out the photos with pathological features by effectively screening endoscopic photos of patients. Background technique: [0002] Due to its small size, light weight, convenient inspection, and non-invasive advantages, capsule endoscopy can be used as the first choice for the diagnosis of gastrointestinal diseases. It has been used in more than 50 countries around the world, and more than hundreds of thousands of patients have received this check. [0003] Capsule endoscopy is actually a miniature camera that transmits image data wirelessly, similar in size and shape to an ordinary capsule. After the patient swallows the capsule, the capsule starts to take pictures of the digestive tract, and transmits the pictures to the receiving device outside the body through radio frequency for storage, and does not stop working until the bat...

AI Technical Summary

Problems solved by technology

Even for an experienced doctor, it takes 2-3 hours to browse through these pictures, and it is inevitable that some information will be missed, resulting in misdiagnosis

With the development of electronic technology and the needs of diagnosis, more photos will be taken per second, and the working time of the capsule will be longer, so the number of photos will increase several times or ten times, which will give doctors more Difficulties in reading diagnostics

At the same time, the cost of the increased workload of doctors must be passed on to the patients, which is one of the reasons why the current cost of capsule endoscopy is too high and there are not many patients who are able to receive this examination

[0005] In fact, the movement of the capsule endoscope in the digestive tract is passive. With the peristalsis of the digestive tract, the capsule advances sometimes fast, sometimes slow, and sometimes even stands still. Therefore, a large number of photographs taken are repeated or similar , of no value for diagnosis
