Post-op liver anatomy with segment 6/7 resected

3D Model

This is a raw CT reconstruction model set made with 3D slicer for a liver resection surgical animation, showing post-operative anatomy following a laparoscopic posterior sectorectomy liver resection in a pediatric patient. We use automated reconstructions for the base level, and then retopologize using ZBrush and Cinema4D.

For this case, the post-op imaging scans provided more detail, so we used what we saw here to augment the lower resolution preoperative anatomy. We don’t always include neighbouring organs such as the spleen and kidneys, but in instances like this where we need to correlate anatomy from separate imaging studies, it helps to include nearby structures as anatomical landmarks to use as points of reference.
