CONSTITUTION:The device is provided with an arithmetic controller 16 which can change a reconstitution arithmetic processing condition used at the time of reconstitution arithmetic processing, in the course of scan, and by allowing it to execute a parallel operation with a scanner controller 15, the reconstitution arithmetic processing condition can be changed even in the course of scan. Also, with regard to measured data 12 obtained by the subsequent scan, the reconstitution arithmetic processing condition. A change of the reconstitution arithmetic processing condition, for instance, a change of an enlarged center position and a change of an enlarged range display a frame-like cursor to an image before change reflected on an image display device 14, and it is executed by operating an instructing device such as a track ball, etc., provided on a console 17.
