Problems solved by technology

The inventors found that when the endoscopist completed the confocal endoscopic observation and prepared to perform a biopsy, he often found that the location of the lesion found under the confocal endoscope could not be determined under the white light endoscope, resulting in the inability to accurately locate the biopsy, resulting in Misdiagnosis and Missed Diagnosis
In clinical operations, sometimes endoscopists use confocal probes to touch the mucosa to make marks, but this method often damages the mucosa and has limited effect

Abstract

The invention provides a confocal laser microendoscope real-time synchronous endoscopic lesion positioning method and system. The method comprises the following steps: receiving an observation start notification of a confocal microendoscope probe, synchronizing a white light endoscope image used for pre-acquiring the current position of a confocal microendoscope probe in real time, caching the image, and calling a pre-trained neural network model to identify a part corresponding to the currently-cached white light endoscope image; and in the confocal microendoscope observation process, judgingwhether a confocal microendoscope lesion discovery notice is received or not in real time: if yes, storing the currently-cached white light endoscope image in a lesion image file storage library andperforming associated storage with the current confocal microendoscope image, and if not, when collecting a next-time observation start notification of the confocal microendoscope probe, enabling a corresponding white light endoscope image replaces the cached white light endoscope image, and continuing to judge whether the confocal microendoscope discovery lesion notification is received or not inreal time.

Description

technical field [0001] The invention belongs to the field of real-time synchronous endoscopic lesion positioning, and in particular relates to a real-time synchronous endoscopic lesion positioning method and system for a confocal laser microendoscope. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Confocal endoscopy can magnify the mucosal structure by 1000 times, observe histological morphology in real time, and accurately diagnose various gastrointestinal mucosal lesions. The inventors found that when the endoscopist completed the confocal endoscopic observation and prepared to perform a biopsy, he often found that the location of the lesion found under the confocal endoscope could not be determined under the white light endoscope, resulting in the inability to accurately locate the biopsy, resulting in Misdiagnosis and missed diagnosi...
