Abstract
Methods and apparatuses for displaying images are provided which input two-dimensional tomographic images of the lower limb including the knee joint, display three-dimensional images of the femur and the tibia including the knee joint from the image input, determine an artificial joint to be replaced from the three-dimensional images of each knee joint of the femur and tibia, and determine various parameters used in an artificial knee joint replacement operation using an alignment rod in the marrow to be inserted into the femur based on the artificial joint and reference points of the knee joint determined when determining a femur side artificial joint.
