Abstract :
In vivo studies of the liver function have been conducted. The data acquisitions have utilized the TomTec Echoscan system to obtain 3D tissue data in addition to ECG and respiration triggered 4D angio and tissue data. Several different algorithmic tools were developed for visualization of tumor and vessel geometry. A fuzzy region growing technique was developed to segment the liver into different anatomical parts. A filtering algorithm was developed to smooth out local intensity variations within the vessels. Different volume rendering techniques were evaluated for visualization
