The proposed process of building a combined knee joint model from CT-derived bone and MRI-derived models using the ICP algorithm. Once the CT-derived model is matched to the MRI-derived model, reference geometries of soft tissue attached to the MRI-derived model will be registered to the CT-derived model. Finally a combined femoral model is composed of CT-derived bone models and MRI-derived soft tissue models or reference geometries.
