Article presents methodology of computer aided destroying focal liver lesions using imaging navigation system. Methodology allows generation of personalized anatomical model of patient’s liver based on CAT screening with contract media of abdominal cavity, registration of edited anatomical model relative to real patient’s position on operation block, presentation of surgical tools position during treatment on the liver’s anatomical model and non-direct monitoring of ablation process of lesions. Liver anatomy model comprises organ’s and focal lesions’ surface and central lines of vascular structures in liver. Generation of personalized patient’s model has been verified based on anonymized abdominal cavity CAT with contrast media screening cases. The registration methodology has been evaluated on imaging data and patient from the Second Department of Clinical Radiology and the Chair and Department of General, Transplant and Liver Surgery at the Medical University of Warsaw after acceptance of the ethics committee of the Medical University of Warsaw.
