Fig. 7: Simulated intraoperative evaluation of resection margins on endoscopic submucosal dissection (ESD) specimens.

a A typical ESD tissue and the three test locations of intra-tumor (T), visual margin (M) and ~8 mm away from the margin (N); b Femto-SRH imaging results of the three test points of a typical case, showing the predicted diagnostic segmentations of cancer (red) vs. non-cancer (blue). c SRH prediction results of the five ESD cases compared with ground truths. Scale bars: 200 µm. Source data are provided in the Source data file.
