<p><P>PROBLEM TO BE SOLVED: To enable fluoroscopic photographing of an X-ray image at the set frame rate from the start of photographing, thereby shortening the time required until the fluctuation of offset becomes stable. <P>SOLUTION: X-rays are emitted from an X-ray emitting means at the start of photographing corresponding to the frame rate set by an operator, and the image of a subject based on the emitted X-rays after transmitted through the subject is detected by a radiation detecting means and is read by a reading means while offset data related to a supplied electric signal is acquired and read. At the start, the photographing is performed at the read frame rate of the electric signal, in which the image of the subject at the start time of photographing and the offset data are combined, higher than the frame rate set before the photographing by the operator, and then transfers to the photographing of the image of the subject at the frame rate set by the operator. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
