摘要

(S101) of inputting a plurality of two-dimensional tomographic images of the lower limb including the pelvis and the femur, an image reconstruction step (S102) of reconstructing a three-dimensional image including the pelvis and the femur from the plurality of two- (S104, S105) for determining the position and orientation of the artificial joint provided on the pelvic acetabulum and the setting from the three-dimensional image of the pelvis and the femur, A base jig setting step (S107 to S109) for setting a three-dimensional image of the base jig having three pillars tangent to the three points of the pelvis; (S110 to S112) for parameterizing and acquiring the direction of the line parallel to the installation direction of the artificial joint.
