Methodological workflow for semi-automated segmentation of the femoral bone. (a) 300 points were randomly selected over the outer surface of the femoral bone on the overview scan. (b) SSM-based segmentation was used for the development of a three-dimensional femoral bone. (c) Manual allocations on the 30° dedicated knee scan resulted in a point cloud that covered the femoral cortex. This point cloud enabled rigid transformation of the femoral mesh, originating from the overview scan, to match the osseous edges. (d) the initial three-dimensional femoral bone was positioned according to the point cloud. The same workflow was applied for 60° and 90° of knee flexion and subsequently for segmentation of the tibial bone.
