In this work, we present a planning tool for liver interventions. It allows for a simulation of the color change on the liver surface after clamping the portal vein at a user defined position. The result is a patient-specific approximation of the (sub-)segmental borders on the liver surface. Furthermore, the impact of different safety margins around a tumor can be simulated to assess the risk of a resection. In addition, it provides delinated portal- and hepatic vein, which can be overlapped to the 2D CT slices, and 3D visualization of the results.
