X-RAY RADIOGRAPHIC APPARATUS AND MAGNETIC RESONANCE IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an X-ray radiographic apparatus corresponding to dynamic 3D-DSA meeting all conditions: that kinetic observation and three-dimensional reconstitution can be performed to be suitable for an intravascular surgery and an in-surgery photography; high spacial resolution is provided; and economical rationality is provided. SOLUTION: The X-ray radiographic apparatus is provided with an X-ray tube apparatus 12 generating X-ray; a tube voltage generation section 13 which generates tube voltage in order to generate X-rays from the X-ray tube apparatus; a two-dimensional X-ray detector 14 which detects X-rays transmitted through a patient; support mechanisms 51 to 54 which support the X-ray tube apparatus and the X-ray detector rotatably surrounding the patient; and a controller 20 which controls the tube voltage generation part, the X-ray detector and the support mechanisms so as to repeat K-times (K is an integer number≥2) of rotating and photographing operation of repeating photographing while the X-ray tube apparatus and the X-ray detector rotatably rotate surrounding the patient while varying a photography-starting angle.
