In the image reconstruction manner in the CT device and the CT device, and the CT

摘要

PROBLEM TO BE SOLVED: To provide a CT apparatus, its image reconstruction method and electronic circuit components to attain faster image reconstruction and higher image quality.;SOLUTION: The CT apparatus to obtain the tomographic images of an object includes a projection data acquisition section to obtain projection data, and an image reconstruction section to obtain the value of each pixel of a tomographic image of the object, based on the projection data acquired by the projection data acquisition section. The image reconstruction section calculates the value x of each pixel as the solution of a differential equation shown below.;COPYRIGHT: (C)2010,JPO&INPIT
