Resection Proposals for Oncologic Liver Surgery based on Vascular Territories

We describe the generation and visualization of resection proposals for oncologic liver surgery which are based on vascular territories of the portal and hepatic vein. Resection proposals are interactively controlled by one parameter: the desired security margin around a tumor. Resection proposals consider vascular structures inside this margin, dependend vascular structures in the periphery as well as the territories supplied by them. The methods have been applied to artificial data from corro sion casts as well as to 5 datasets obtained in the clinical routine from 3 hospitals.
