X-RAY DIAGNOSTIC IMAGING APPARATUS, AND ITS THREE-DIMENSIONAL BLOOD FLOW IMAGE CONSTITUTING/DISPLAYING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an X-ray diagnostic imaging device which three-dimensionally observes the blood flow kinetics of a desired blood vessel in a blood vessel imaging inspection.;SOLUTION: This X-ray diagnostic imaging device is equipped with a control section 1A, a console 1B, an image processing section 15, and an image displaying section 16. In this case, the control section 1A obtains first X-ray transmission data at every specified rotation angle of a holder 17 under a state in which a contrast agent is not injected, and stores each first X-ray transmission data in a storage section 151 of an image processing section 15. In addition, the control section 1A performs a control in such a manner that second X-ray transmission data may be obtained at every specified rotation angle of the holder 17 under a state in which the contrast agent is injected in a subject 12. The console 1B sets a range for the rotation angle of a blood vessel imaging image which is calculated at every rotation angle of the holder. The image processing section 15 calculates a differential image between the second X-ray transmission data and the first X-ray transmission data which is stored in the storage section 151 as a blood vessel imaging image at every rotation angle, and at the same time, constitutes a three-dimensional blood flow image from the blood vessel imaging image in the range of the rotation angle which is set by the console 1B. The image displaying section 16 displays the three-dimensional blood flow image which is constituted by the image processing section 15.;COPYRIGHT: (C)2007,JPO&INPIT
