Title:
GALLBLADDER POLYP DETERMINATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/140449
Kind Code:
A1
Abstract:
According to embodiments of the present invention, a gallbladder polyp determination system may be provided, the gallbladder polyp determination system comprising: a collection unit which collects abdominal ultrasound images of gallbladder polyps labeled with true polyps or pseudopolyps; a data generation unit which generates, on the basis of the abdominal ultrasound images, input data to be input to a gallbladder polyp classification model, which is an ensemble model including n prediction models (where n is an integer of 2 or more); a model training unit which trains the gallbladder polyp classification model by using the input data; and a classification unit which classifies an abdominal ultrasound image of a new gallbladder polyp as a true polyp or a pseudopolyp by using the gallbladder polyp classification model.
