Abstract:
1. An ultrasound diagnostic apparatus comprising: an image data generation unit configured to generate image data corresponding to one frame of a tomographic plane of a subject, based on sound ray data acquired by transmitting ultrasound to the subject to which an ultrasound contrast agent is administrated; a high intensity image determination unit configured to compare a strength of sound ray data corresponding to the one frame with a predetermined value and thereby determine whether the one frame is a high intensity image; a setting unit configured to set a region of interest onto an image based on the image data generated by the image data generation unit; and a time intensity curve arithmetic unit configured to perform an arithmetic operation on a time intensity curve which indicates changes in pixel values of the region of interest based on the image data for each of a plurality of frames, wherein image data of the region of interest in a frame that is determined to be the high intensity image is eliminated from the time intensity curve.
