摘要:
A computer is caused to execute an image inputting step (S101) of inputting a plurality of two-dimensional tomographic images of the lower limbs including the pelvis and the femur, an image reconstructing step (S102, S103) of reconstructing a threedimensional image including the pelvis and the femur from the plurality of two-dimensional tomographic images, an artificial joint determining step (S104, S105) of determining an artificial joint which is to be set to the acetabular cartridge of the pelvis, a setting position, and a setting direction from the three-dimensional image of the pelvis and the femur, a base jig setting step (S107-S109) of setting a three-dimensional image of a base jig having three support columns which are in contact with three landmarks of the pelvis with respect to the three-dimensional image of the pelvis, and a parameter obtaining step (S110-S112) of parameterizing and obtaining a direction of a line which passes through the upper end of a support column in immediate proximity to the acetabular cartridge of the pelvis in the three-dimensional image of the base jig and is parallel to the setting direction of the artificial joint.
摘要:
Steps S101 and S102 of displaying images which input two-dimensional tomographic images of the lower limb including the knee joint and displays three-dimensional images of the femur and the tibia including the knee joint from the image input, steps S103 to S105 and S106 to S108 of determining artificial joint which determine the artificial joint to be replaced from the three-dimensional images of each knee joint of the femur and tibia, and steps S113 and S114 of parameter determination which 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 in steps S103 to S105 of determining femur side artificial joint are performed by a computer.
