Size of Long Image with Exposure

When the "Line Scan Type X-ray Diagnostic Equipment" of JSB is applied, there will ideally be no limit to the length of the subject. In case of equipment under development by JSB, radiographic imaging of a subject with a maximum length of 100 mm with line width of 410 mm is possible at 2,048 x 5,000 pixels. This means that taking X-rays of long subjects such as the leg bones or the vertebrae will be easily possible. Also, despite the subjects being great at length, the total time it takes to take an X-ray is less than 10 sec., even with image processing time. It is also easier to operate when compared to the existing method of moving the subject to different positions or using many units of FPD. Actually, the diagnostic equipment developed by JSB has been under clinical trial at a hospital in Seoul, and the results of time or images have been rated to be much more satisfactory when compared to the CR (Computed Radiography) system previously used in that hospital. When compared to the existing CR equipment, the time it took to take X-rays per person was as short as 1/5, significantlydiminishing the time spent to take X-rays over a 1 year period. On the contrary, when the scan-DR equipment is used, taking more X-rays during a given period is possible, thus resulting in the increase in efficiency in hospital operation. Because many X-ray photos are attached together to show the final photo when CR equipment is used, disconnections in the final image are inevitable, which is also the case with FPD or CCD detectors. However, when the Scan-DR is used to take X-rays, there will be no disconnections due to its scan method, resulting in clear images.
