<P>PROBLEM TO BE SOLVED: To improve a distance resolution, sensitivity, a clutter removing effect, and a frame rate, in a power Doppler. <P>SOLUTION: An ultrasonograph comprises: an ultrasonic probe 1; transmitting/receiving circuits 2, 3 for scanning a subject with ultrasonic waves via the ultrasonic probe; a B-mode processor 4 for generating B-mode data based on reception signals outputted from the transmitting/receiving circuits; a power Doppler processor 5 for generating power Doppler data on the basis of the reception signals that are outputted from the transmitting/receiving circuits and collected under a transmission condition that a burst wave number is the same as or substantially same as the B-mode data; a composition part 7 for partially compositing the B-mode data and the power Doppler data and generating one frame of composite image data; and a display device for displaying the composite image data, which displays the part of the B-mode data using a display map of a gray scale, and displays the part of the power Doppler data using the display map same as the display map. <P>COPYRIGHT: (C)2013,JPO&INPIT |
