Diagnosis of Liver Tumor Using 3D Segmentation Method for Selective Internal Radiation Therapy

This paper introduces 3-D liver segmentation method for selective internal radiation treatment as the treatment for liver tumors. In treatment of liver cancer, delivering maximum radiation dose to the tumor and minimum toxicity to the surrounding healthy tissue is of great difficult in clinical practice. This can be eliminated by 3-D segmentation method for accurate calculation of functional tumor volume and anatomical volume of the liver for determination of the tumor to normal liver ratio and consequently for the calculation of the dose to the patient. It uses region growing method with threshold algorithm. 3-D liver segmentation is vital in computer assisted surgery applications such as minimal invasive surgery, tumor resection, targeted drug delivery and donor liver transplantation.
