<p><P>PROBLEM TO BE SOLVED: To reduce contrast imaging load of a subject in performing contrast rotary photographing twice or more times. <P>SOLUTION: This X-ray diagnosis apparatus includes: a substantially C-shaped arm 60; a support mechanism 22 rotatably supporting the substantially C-shaped arm; a rotary driving part 23 for driving the rotation of the substantially C-shaped arm; an X-ray tube 12 mounted to the substantially C-shaped arm; a high voltage generating part 26 for generating high voltage for generating X-rays from the X-ray tube; an X-ray detector 10 mounted to the substantially C-shaped arm opposite to the X-ray tube; and a rotary photographing control part 20, which controls the operation of the support mechanism, the high voltage generating part and the X-ray detector for repeating two or more times the rotary photographing operation of continuously or intermittently generating the X-rays from the X-ray tube while rotating the substantially C-shaped arm and repeating the X-ray detection by the X-ray detector after single injection of a contrast medium, and performs the time control management each of the rotary photographing operation two or more times according to the time taking the time of the single injection of the contrast medium as a starting point. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
