Analysis of 4-D CT Images Degraded by Motion Artifacts

4-D computed tomography (CT) scanner provides a dynamic volumetric imaging and good contrast detectablity with a high speed for collecting projections. In spite of these merits, some motion effects such as respiration, cardiac motion, and patient restlessness produce artifacts that appear as blurrin...
