A: 3D reconstructed image of the intrahepatic vessels and tumor from dynamic CT images. Blue, portal vein; White, hepatic vein; Brown; the tumor; Red broken line, cut line for resection of segment 7. B: Simulation of the anatomical resection of segment 7, shown as the purple area. C: ultrasound guidance (IOUS) image, with the yellow arrow showing the regional Glissonian pedicle of segment 7. D: The 3D printed model of the intrahepatic vessels being used in the operative field. E: The 3D printed model of the intrahepatic vessels after painting specifically for the figure. F: Transected surface of the liver, with the yellow arrow showing the regional Glissonian pedicle of segment 7 after cutting.
