Abstract

Instead of a phantom with a fixed joint, a positioning doll that is the size of an actual adult and has movable joints can be used to practice positioning for radiography. This paper describes the image processing of a knee joint image created from computed tomography (CT) data using a positioning doll in order to provide the radiographic practice which bend the knee joint. First, pre-processing is performed to adjust the transverse plane images obtained by the CT scanner. Next, the adjusted transverse plane image is divided into the femur, patella, tibia and fibula parts. They are reconstructed according to the angle of bending, and the lateral knee joint image is produced. Various images of different angles of the knee joint and different angles of body rotation can be produced from CT data. It is expected that students will grasp the three-dimensional structure of the organ to be examined and deepen their anatomical knowledge by using our proposed method. We believe this method will help students learn positioning techniques.
