CT image based training tool for positioning in radiography

An appropriate and quick positioning technique is essential for obtaining accurate diagnostic information in radiography. In this study, a computed tomography (CT) image-based training tool which can assist the students is developed and the X-ray training method using CT images for positioning in radiography is proposed. First, from the CT image data of the phantom scanned beforehand, the three-dimensional (3D) phantom using solid model is constructed and the positioning on a personal computer (PC) using the 3D phantom is performed. Next, the plane image corresponding to the displayed phantom position from the CT image data is calculated. By using our developed tool, it is expected that students could perform the positioning training without having to expose X-rays and develop the films.
