Abstract

In the present invention, an image processing device is configured by including an ultrasonic wave transmitting section, an ultrasonic wave receiving section, a transmission and reception control section, a B mode signal processing section, a B mode image generating and storing section, an image synthesizing section, a Doppler signal processing section, a Doppler image generating and storing section, a Doppler scan region setting section, a Doppler scan region storing section, a Doppler scan control section, a region marker movement control section and a region marker image generating section. By the configuration, an observation target of which blood state needs to be grasped can be always optimally observed in real time in a Doppler image by a Color Doppler mode or a Power Doppler mode.
