Study of Positioning Techniques for Skull Radiography using CT images

We describe a new method of positioning techniques in radiology. The positioning technique is important in obtaining an accurate diagnostic information. It is desirable to perform the positioning accurately. As X-ray films are usually used in radiography, the development of the films becomes necessary. In this study, we propose a new positioning training method using digital image processing. We scan the skull phantom by CT and obtain the CT images. We produce the necessary plane images for diagnosis from CT images. We develop a method which produces the plane image of the phantom placed under the X-ray tube in real time. Our method is useful for helping the positioning practice as a teaching material without X-ray exposure and development of X-ray films.
