<p>In order to detect whether the center position of a subject is offset from a scan center and notify a human operator of the result of the detection, the subject center position is detected based on a projection profile of a parallel view at a view angle of 90° (S5). If the distance between the subject center position and the scan center exceeds a predefined range (e.g., 50cm) (S6), a warning is display on a CRT to prompt the operator to adjust the position of the subject and repeat imaging (S7).</p> |
