X-ray computed tomography apparatus with support system for setting scan conditions |
摘要 |
<p>An X-ray computed tomography apparatus is provided to reconstruct image data based on projection data acquired by scanning a subject with an X-ray. A calculator (118) is configured to calculate a dose efficiency index based on an expected dose of an X-ray entered using an input device (115). The dose efficiency index indicates a diameter of a target which is identified at a predetermined detectability rate and has a predetermined CT value difference with respect to a surrounding CT value. A plan support system (117) is configured to build up a scan planning screen on which the input expected dose is contained along with the calculated dose efficiency index. The scan planning screen is displayed on a display (116). <IMAGE></p> |
