In radiography the human body must be accurately and quickly positioned under X-ray equipment in order to obtain an image of the examined organ. The good positioning skill of the radiological technologist is essential for obtaining accurate diagnostic information of an examined organ and for reducing X-ray exposure in radiography. In this study, we developed a computed tomography (CT) image-based...
A good positioning technique is essential for obtaining accurate diagnostic information in radiography. In this study, we developed the imaging techniques which produce a plane image using CT images in order to assist the students' positioning practice under the X-ray equipment. First, we scanned the skull phantom by CT (computed tomography) and obtained CT images. Next, we measure the positioning...
The mammographic X-ray equipment uses a radiographic grid in order to remove the scatter radiation and improve image contrast. The grid causes striped lines to appear on the film and may degrade diagnostic information. In this study, we propose a new method which reduces the noise caused by the grid on mammographic film using non linear image filtering. We performed median filtering and the V-filtering...

The mammography X-ray equipment uses a radiographic grid in order to remove the scatter radiation and improve image contrast. The grid causes striped lines to appear on the film and may degrade diagnostic information. In this study, we propose a new method which reduces the noise caused by the grid on mammographic film using digital image processing techniques. We considered a method of eliminating...

We describe a new method of positioning techniques in this paper. The positioning technique is important to obtain accurate diagnostic information in radiography. As X-ray films are usually used in radiography, the development of the films becomes necessary. It is desirable to perform the positioning accurately and to confirm the results of the positioning in short time. In this study, we construct...
