Pyloric state detection system applying signal analysis

Abstract

The invention relates to a pyloric state detection system applying signal analysis, and the system comprises a content extraction mechanism which is used for calculating the entity area of a pyloric target based on a received photographing focal length, the overall depth of field, and the number of reference pixels; a radius identification equipment which is connected with a content extraction mechanism and is used for calculating the radial radius of the pyloric target based on the shape of the to-be-analyzed region corresponding to the pyloric target and the entity area of the pyloric target; and an anomaly detection mechanism which is connected with the radius identification equipment and is used for sending a pylorus anomaly instruction when the absolute value of the difference value between the maximum radial radius and the standard pylorus radius exceeds a limit. The pyloric state detection system applying signal analysis is simple to operate and wide in application. The targetedrecognition mode can be adopted to perform recognition operation on the pylorus radius of the patient according to the pylorus shape of the current patient and the pylorus entity area of the currentpatient, whether the pylorus of the current patient is in a diseased state or not can be judged.

Description

technical field [0001] The invention relates to the field of gastroscope application, in particular to a pyloric state detection system using signal analysis. Background technique [0002] Gastroscopy is a method of medical examination and also refers to the equipment used in this examination. It is inserted into the stomach through a thin, flexible tube, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for minor lesions. Gastroscopy can directly observe the real situation of the inspected part, and can further confirm the diagnosis through pathological biopsy and cytological examination of suspicious lesions. It is the preferred inspection method for upper gastrointestinal lesions. [0003] The earliest gastroscope is the Kussmore tube invented by the German Kussmore in 1868, which is actually a long metal tube with a mirror at the end. But because this kind of gastroscope is easy to puncture the patient's esophagus, it was ...

AI Technical Summary

Problems solved by technology

[0004] The current gastroscopy treatment institutions cannot use the targeted recognition mode to perform identification operations on the patient's pyloric radius according to the current patient's pyloric shape and the current patient's pyloric solid area, and thus cannot judge the current state of the current patient's pylorus
