Figure 2 Schematic representation of artificial intelligence-driven anatomic delineation of hepatocystic triangle using bounding box and semi-transparent overlay mask. A: Initial bounding box method (red rectangle) for broad target area identification and a confidence call out; B: Semantic segmentation further precisely defining the exact region of hepatocystic triangle (HCT) by using a semi-transparent optical density mask overlay.
