AI Medical Service Inc. Announces Release of Gastric AI-based Endoscopic Diagnosis Support System

AI MEDICAL SERVICE INC. (hereinafter AIM), a medical start-up specializing in the development of diagnostic endoscopic AI, is excited to announce the release of an AI-based endoscopic diagnostic support device that operates within the stomach (brand name: gastroAI-model G, registration number: 30500BZX00297000) on March 4, 2024. The endoscopic AI (hereinafter gastric cancer diagnosis support AI) assists the physician in diagnosis of neoplasia by detecting lesion candidates for biopsy[1] or other additional diagnostic steps based on gross visual features during endoscopy. 

About gastric cancer diagnosis support AI “gastroAI-model G” 

AIM has launched the gastric cancer diagnosis support AI, brand-named “gastroAI-model G,” with the manufacturing and marketing approval by Japan’s Minister of Health on December 26, 2023 (Registration number: 30500BZX00297000). 

The software was developed based on training data provided by world-class medical institutions, utilizing deep learning technology and the support of more than 100 institutes for collaborative research. 

The AI works by scanning for candidate lesions using a general-purpose computer, using images extracted from the endoscopy system’s video processor. When the program calculates that a lesion is suspicious for early gastric cancer and warrants further workup, it alerts the physician and provides diagnostic assistance by displaying a rectangle inside the endoscopic display area.
