Abstract

See full text

An ultrasound diagnostic apparatus according to an embodiment includes an ultrasound probe and processing circuitry. The ultrasound probe sequentially executes sets of ultrasound transmission respectively along a plurality of scan lines, the sets each being composed only of transmission of first ultrasound having a first phase and transmission of second ultrasound having a second phase that is substantially 90 degrees different from the first phase. With respect to a first echo signal and a second echo signal that have been obtained via the ultrasound probe and correspond to the first ultrasound and the second ultrasound, respectively, the processing circuitry generates a subtraction signal by subtracting the second echo signal from the first echo signal. The processing circuitry generates an ultrasound image based on the subtraction signals generated for the scan lines.
