Automatic boundary extraction from magnetic resonance images of the residual limb of a trans-femoral amputee

Information about the relative locations of different tissue types in the residual limb is required for biomechanical analysis of the interaction between the limb and the prosthetic socket. An automatic method for the extraction of the boundaries of muscle, fat, and bone from transverse magnetic resonance images of the residual limb of a unilateral trans-femoral amputee is presented. Median filtering is applied for smoothing, segmentation is achieved by k-means clustering, and boundaries are extracted using mathematical morphology
