Verification of precision of wear measurement of the hip arthroplasty using three-dimensional scanning

Medical operation of THA is change of a acetabular cap and a femoral head to the hip arthroplasty (artificial joint ). It's one of the operations when a thigh joint became worse. The wear of this artificial joint brings a serious difficulty to the human body. GAWDI which we developed is the non-destruction inspection software that wear of the artificial hip joint is measured from the Roentogen image. We developed a method to measure wear distance of figure data which is obtained by scanning using 3D scanner the weared arthr9plasty extracted in revision operation to verify the
