Study on Digital Reconstruction of Anatomical Structure of Liver

A semi-automatic digital liver reconstruction method based on CT serial images for hepatobiliary is presented. Firstly, interesting regions such as liver, blood vessels and tumor are segmented by machine. Then, blood vessels are identified interactively with doctor's points. A 3D minimum distance is used to partition the sub-area of liver that blood vessel branches supply. As a result, a 3D virtual liver with vascular trees, tumor, and liver segments is reconstructed. This model was compared with real liver of clinical surgery. Experiments show that this 3D liver model promotes the precision of hepatobiliary surgery and may be used for other interventional therapies in the treatment of liver disease.
