X-RAY DIAGNOSTIC APPARATUS AND X-RAY IMAGING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus and an X-ray imaging method wherein the projection data from more directions at a predetermined palmic time-phase are collected and the obtained projection data are reconstructed to enable higher quality X-ray image data to be generated. SOLUTION: Projection data are obtained by using a method for imaging by rotating a first imaging system having an X-ray generating unit 1a and a second imaging system having an X-ray generating unit 1b. The obtained projection data are subjected to a reconstruction process to generate X-ray image data. In this case, a relative angle η0 formed between the imaging systems is setup according to a palmic period T0 of a subject and a turning velocity Vr of the imaging systems. Thus, the projection data from more directions at a predetermined palmic time-phase are collected without overlapping. COPYRIGHT: (C)2006,JPO&NCIPI
