<P>PROBLEM TO BE SOLVED: To provide reducing displacement of an area for detecting arrival of a contrast medium, and performing photography in proper timing. <P>SOLUTION: An area-setting scan A is executed, and the area is set in a section while referring to an image displayed on a display screen. After setting the area, a baseline scan is executed, and a baseline BL of signal strength before the contrast medium arrives at the area and a threshold value TH for deciding whether or not the contrast medium has arrived at the area are determined. After the baseline scan B ends, a contrast medium arrival detection scan C for detecting whether or not the contrast medium has arrived at the area is executed, and if it is decided that the contrast medium has arrived at the area, it is determined that an actual scan D will be started. <P>COPYRIGHT: (C)2012,JPO&INPIT |
