Model Based Auto Segmentation of Knee Bones and Cartilage in MRI Data


We present a method for fully automatic segmentation ofthe bones and cartilages of the human knee from MRI data. Based onstatistical shape models and graph-based optimization, first the femoraland tibial bone surfaces are reconstructed. Starting from the bone sur-faces the cartilages are segmented simultaneously with a multi objecttechnique using prior knowledge on the variation of cartilage thickness.We validate our method on 40 clinical MRI datasets acquired before kneereplacement.
