Outline of Final Research Achievements

X-ray computed tomography (CT) equipment is currently used in everyday clinical settings to visualize internal tissues of the human body and the education and practical training in educational institutions that train medical radiological technicians normally employ actual equipment. However, it is not necessarily easy for students to understand the configuration of X-ray CT equipment or the principle behind image reconstruction, and easy-to-use experimental equipment for educational purposes that combine a CT system and image-processing system are hardly found at training sites. We planned the development of a new educational system that could simulate X-ray CT equipment and constructed a working simulation system that could be used in student experiments. This system can simulate an X-ray fan beam with line-shaped laser light, reconstruct images based on a conventional scan or helical scan, and perform experiments on the effects of helical pitch or on the generation of artifacts.
