An ultrasound diagnostic apparatus for obtaining an ultrasound image of a subject
into which an ultrasound contrast agent mainly composed of microbubbles is injected,
comprising a probe configured to transmit/receive an ultrasound wave to/from the
subject, a transmission circuit configured to drive the probe to transmit an ultrasound
wave while sequentially changing a direction of an ultrasound transmission line,
a reception circuit configured to generate reception line data of the number of
parallel reception from ultrasound echo signals obtained by one ultrasound wave
transmission, a transmission/reception control circuit configured to control the
transmission and reception circuits to change the number of parallel reception
during a scan sequence for generating a 1-frame ultrasound image, and an image
processing unit configured to generate an ultrasound image on the basis of the
reception line data.
