PROBLEM TO BE SOLVED: To improve visibility by making a tomographic image into an image in a first color, the displacement of tissue into an image in a second color and bloodstream distribution into an image in a third color, respectively based on an ultrasonic reception signal from an examinee and displaying by layering respective image. SOLUTION: An ultrasonic wave probe 100 radiates an ultrasonic pulse on the examinee, and separates the ultrasonic reception signal corresponding to a frequency component with a filter 120 after receiving the signal from the examinee. A B-mode image is generated by applying B-mode processing to a low-pass area component by a B-mode processing part 131, and a tissue displacement image is generated by applying MTI processing to a middle-pass area component by an MTI processing part 132 for tissue displacement. Moreover, a bloodstream distribution image is generated by applying the MTI processing to a high-pass area component by a MTI processing part 133 for bloodstream, and after that, tomographic images, tissue displacement images and bloodstream distribution images with different colors are layered, then, they are displayed on a display part 170. |
