CTによる動きの描出

概要

論文の詳細を見る
Double-contour images of the aortic root can be seen on the chest computed tomograms (CTs) (full-scan images). And some of them became unclear on each reconstructed half-sacn image. The major cause of these artifacts is cardiac motion. We simulate these artifacts with moving phantom and with the drawings of the trajectory geometries from the view of Gantry (X-ray tube and detectors). CT displays the moving object truly as its trajectory geometry from the view of Gantry.総説Review Article
