Applications of pelvic 3D reconstruction and dimension measurement to colorectal cancer surgery.

Three-dimensional visualization is opening new worlds for more precise diagnosis and higher-quality treatment. 3D reconstruction from medical images is widely used in diagnosis and medical research. This paper focuses on 3D surface reconstruction of the pelvis from CT images on a personal computer. We measure and analyze large numbers of interrelated parameters in order to help doctor in diagnosis, operation planning and the actual surgery.
