Semi-Automatic Segmentation of the Patellar Cartilage in MRI

A software system for semi-automatic segmentation of the patellar cartilage is introduced. Providing tools for sub-pixel accurate edge tracing, automatic contour completion, and adequate visualization we achieve a remarkable speed-up of the physician’s segmentation process. The exactness for cartilage segmentation can be reached if expertise and automation are merged in a meaningful way.
