摘要 |
In order to obtain an X-ray tomographic image with high quality while minimizing the exposed dose to a subject by employing the most suitable filter according to the region of the subject to be scanned, a filter unit <HIL><PDAT>6 </BOLD><PDAT>having filters <HIL><PDAT>6</BOLD><HIL><PDAT>a-</ITALIC><HIL><PDAT>6</BOLD><HIL><PDAT>c </ITALIC><PDAT>having different transmission properties are provided below an X-ray tube <HIL><PDAT>4 </BOLD><PDAT>in a gantry apparatus. To obtain an X-ray tomographic image, upon determining the scan region of the subject, a motor <HIL><PDAT>7 </BOLD><PDAT>is driven to position one of the filters corresponding to the scan region just below the X-ray tube <HIL><PDAT>4 </BOLD><PDAT>for employing the filter, and X-rays are applied to the subject through the filter.</PTEXT>
