<P>PROBLEM TO BE SOLVED: To capture a high-quality radiation image by properly setting the dose of a radiation image throughout a series of imaging, when the radiation images of a plurality of frames are captured by continuously irradiating a living body, in which a contrast medium is injected, with radiation. <P>SOLUTION: The radiation image signal for each frame detected by a radiation image detector 12 is acquired by radiation imaging for continuously irradiating a living body, in which the contrast medium is injected, with radiation, and the irradiation dose of the radiation is controlled on the basis of the acquired radiation image signal for each frame or the detection signal output from a radiation detector for detecting the radiation transmitted through the living body. In this case, a frame containing the image signal representing the image of the contrast medium in the radiation image signal for each frame is specified as a contrast medium frame. During imaging the contrast medium frame, the dose of the radiation is kept constant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
