Method, system and computer readable medium for evaluating colonoscopy performance

An artificial intelligent system for evaluating colonoscopy performance, comprising:

• an input device configured to acquire a video during a colonoscopy examination;
• and
• a computing device in communication with the input device, the computing device comprising a server having a processor and a memory coupled to the processor, the memory having a computer program stored therein, wherein when the computer program is executed, the processor is controlled to perform steps of:
• (S1) splitting the video acquired by the input device into a plurality of colonoscopy images;
• (S2) assigning each of the colonoscopy images into an inadequate-view group or an adequate-view group according to a first classification criterion, and assigning each colonoscopy image in the adequate-view group into a fold-inspection group or a lumen-inspection group according to a second classification criterion,
• wherein the first classification criterion comprises at least one of clarity, exposure, level of tissue wrinkling, and level of occlusion in each of the colonoscopy images;
• the second classification criterion comprises at least one of an amount of haustrum, an amount of colonic lumen, and a position of the colonic lumen in each of the colonoscopy images and
• wherein the colonoscopy image in the adequate-view group is assigned into the fold-inspection group if the colonoscopy image meets one of the requirements of:
• (R1) colonic wall is shown, but in absence of haustrum or colonic lumen;
• (R2) colonic wall and haustrum are shown, but in absence of colonic lumen;
• and
• (R3) colonic wall, haustrum and colonic lumen are shown, the amount of the haustrum shown falls within a range of 1 to 5, and the colonic lumen falls outside of a central area of the colonoscopy image;
• or
• the colonoscopy image in the adequate-view group is assigned into the lumen-inspection group if the colonoscopy image does not meet any of the requirements of (R1)-(R3);
• and
• (S3) determining a performance rating of the colonoscopy examination according to an elapsed time of at least one of the fold-inspection group, the lumen-inspection group, and the inadequate-view group.

A non-transitory computer-readable medium for evaluating colonoscopy performance, comprising a computer program stored therein, wherein when the computer program is executed, a device installing the non-transitory computer-readable medium is controlled to perform steps of:

• (S1) splitting a video acquired during a colonoscopy examination into a plurality of colonoscopy images;
• (S2) assigning each of the colonoscopy images into an inadequate-view group or an adequate-view group according to a first classification criterion, and assigning each colonoscopy image in the adequate-view group into a fold-inspection group or a lumen-inspection group according to a second classification criterion,
• wherein the first classification criterion comprises at least one of clarity, exposure, level of tissue wrinkling, and level of occlusion in each of the colonoscopy images;
• the second classification criterion comprises at least one of an amount of haustrum, an amount of colonic lumen, and a position of the colonic lumen in each of the colonoscopy images, and
• wherein the colonoscopy image in the adequate-view group is assigned into the fold-inspection group if the colonoscopy image meets one of the requirements of:
• (R1) colonic wall is shown, but in absence of haustrum or colonic lumen;
• (R2) colonic wall and haustrum are shown, but in absence of colonic lumen;
• and
• (R3) colonic wall, haustrum and colonic lumen are shown, the amount of the haustrum shown falls within a range of 1 to 5, and the colonic lumen falls outside of a central area of the colonoscopy image;
• or
• the colonoscopy image in the adequate-view group is assigned into the lumen-inspection group if the colonoscopy image does not meet any of the requirements of (R1)-(R3);
• and
• (S3) determining a performance rating of the colonoscopy examination according to an elapsed time of at least one of the fold-inspection group, the lumen-inspection group, and the inadequate-view group.
