Abstract:
1. 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 transmit an ultrasound wave to form a period during which a contrast agent flows into the object and a period during which microbubbles are collapsed by an ultrasound wave and driving said probe to perform ultrasound transmission so as to obtain ultrasound echo data corresponding to a plurality of frames in the microbubble collapse period; and an image generating unit configured to generate images of the plurality of frames on the basis of ultrasound echo signals received by said probe and a combined image by combining the plural images, wherein said image generating unit is configured to generate said combined image by comparing the images of the plurality of frames with each other and setting a luminance I(x, y) of the combined image according the relationship I(x, y)=MAX (I
