Abstract:
1. An X-ray diagnosis apparatus, comprising: a radiography unit including an image data generating unit configured to generate at least one of 2D and 3D image data based on an output from said X-ray detection unit; a displaying unit that displays the 3D image data; an ROI setting unit configured to set a region of interest on the displayed 3D image in accordance with a user instruction; a mechanism configured to move said radiography unit, including rotating the arcuated arm; and a controller configured to control said collimator based on a position and a size of the set region of interest so as to adjust the irradiation field to a range corresponding to the set region of interest, and to control said mechanism based on the position and the size of the set region of interest, wherein said controller controls said collimator during the scan in accordance with a rotation of the arcuated arm so as to position a center of the set region of interest at a center of the camera system of the X-ray diagnosis apparatus at each of the projection angles in the scan; and wherein said controller controls an aperture of said collimator for each of the plurality of projection angles in the scan so that only the set region of interest is irradiated at each of the plurality of projection angles in the scan.
