X-ray diagnostic apparatus and radiation diagnostic apparatus |
摘要 |
An X-ray diagnostic apparatus forms image data using an arbitrary region in the detectable area of a planar detector having a plurality of X-ray detector elements arrayed in a matrix. An X-ray sensor array for exposure-controlling having a plurality of X-ray sensors arrayed in a matrix overlaps the planar detector. An X-ray controller controls an X-ray tube unit on the basis of an output from the X-ray sensor array in order to optimize the X-ray dose on a subject. A controller selects at least one X-ray sensor in accordance with the position of a partial region where an image is formed. The controller controls at least one of the X-ray sensor array and X-ray controller so as to control the X-ray dose on the basis of an output from the selected X-ray sensor.
