Background: Accurate measurement of early gastric cancer (EGC) size is important for clinical management. We evaluated a computer vision-assisted virtual ruler (VR) for measuring lesion size during endoscopy. Methods: This prospective clinical trial included 78 patients who underwent endoscopic submucosal dissection (ESD) from January to December 2024. The maximum diameter of the post-ESD specimen, measured with a physical ruler, was used as the reference. VR measurements obtained during ESD and preoperative vis…
The gain
In a prospective study of 78 patients, a computer vision virtual ruler measured early gastric cancer lesions with a mean absolute error of 1.00 mm versus 3.00 mm for visual estimation.

How to check it yourself, without trusting this page
Download any version from /api/record/TRV-2026-2473 and hash its canonical field yourself, for example with shasum -a 256. You should get its content_hash. Each version’s text also ends with prev:and the hash of the version before it (version 1 points to 64 zeros). If anyone had changed a single character of any version after it was saved, those hashes wouldn’t line up.
