Abstract: PROBLEM TO BE SOLVED: To form up concurrently the images of tissue and blood current by providing the subject device with an image processor to make B mode display data on processing ultrasonic echo and a Doppler processor to make Doppler display data on processing the same echo and forming a three-dimensional image on processing both outputs. SOLUTION: A scan head 10 is to transmit ultrasonic pulse into the human body equipped with a converter array 12 to receive ultrasonic echo. After the received echo signal is filtered by I, Q filter 20, I, Q specimen is processed by a gray scale mapping circuit 24 in B mode process. In Doppler process, it's processed on band filter by a wall filter 22 and gathered to the Doppler data aggregation in a Doppler processor 30. Perspective parameter is then input to perspective parameter memory 52, 54, image data of the tissue and blood current are put together and formed up to a three-dimensional image in a three-dimensional combination image fluoroscopy processor 50.
