abstract = {Preoperative planning for liver surgery is a critical procedure to assess a potential resection and it supports surgeons to define the affected vessels and resection volume. Traditional surgical planning systems are widely used to support the planning with the usage of desktop-based 3D and 2D visualizations.

The virtual re-section is further refined to keep safety margins from the tumors. Moreover, real-time risk maps are visualized to support the surgeons during the modification.

Preoperative planning for liver surgery is a critical procedure to assess a potential resection and it supports surgeons to define the affected vessels and resection volume.
