Accurate positioning reduces the X-ray
exposure of the subject and produces a valuable X-ray image for diagnosis. This
paper describes the development of a positioning training tool that supports
those studying to be radiological technologists in learning the positioning
technique efficiently. Students perform the positioning on a personal computer
using a three-dimensional computer graphics (3DCG) phantom constructed from
computed tomography (CT) image data and confirm the produced plane image
corresponding to the positioned phantom. It is expected that students will be
able to undertake positioning training using our tool anywhere and at any time
without using X-ray equipment. Repeated use of our training tool will help
students attain a deep understanding of anatomy and acquire positioning skills
efficiently and accurately.
