摘要：
This paper analyzes the degradation of reconstructed images and artifacts due to the rotary motion of a rigid object. The degradation of a CT image caused by rotation of an arbitrarily shaped rigid object is formulated by using a point-spread function. The characteristics of blurred images of a rigid object due to its rotation in a CT and the shape of blurred images also are analyzed. The cause of stroboscopic images is explained by using line sources. The theories have been confirmed by computer simulation.
