<P>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which obtains an ultrasonic Doppler image wherein an influence of a residual echo is removed or reduced by the smaller increase of a scanning time when scanning by an ultrasonic Doppler method while the transmission interval of ultrasonic waves about the same raster direction is made to be an unequal interval, and to provide a control program of the ultrasonic diagnostic device. Ž<P>SOLUTION: The ultrasonic diagnostic device is provided with a data acquisition means, a data correction means, and a blood flow information acquisition means. The data acquisition means transmits and receives the transmission waves by the unequal intervals a plurality of times about the same raster direction and varies raster directions (a), (b), (c), an (d) of transmitting and receiving the ultrasonic waves, thereby acquiring Doppler reception data (shaded portion) and a correction echo (portion shaded with diagonal lines) from a plurality of raster directions. The data correction means corrects the reception data (shaded portion) using the correction echo (portion shaded with diagonal lines), thereby acquiring the Doppler reception data wherein the residual echo is removed or reduced. The blood flow information acquisition means acquires blood flow information from the Doppler reception data wherein the residual echo is removed or reduced. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž |
