1. An ultrasound diagnostic apparatus, comprising image processing circuitry configured to:
perform a first ultrasound scanning on a subject, a second ultrasound scanning, and a third ultrasound scanning during a scanning sequence in a time-division manner;
acquire, based on a result of the first ultrasound scanning, blood flow information at each position within a first region of the subject;
acquire, based on a result of the second ultrasound scanning, morphologic information at each position within a second region which overlaps with the first region of the subject and is larger than the first region;
acquire, based on a result of the third ultrasound scanning, tissue property information at each position within a third region which corresponds to the first region of the subject and is smaller than the second region, wherein the tissue property information is information based on propagation of shear waves in the subject induced by acoustic radiation force applied to the subject, the third ultrasound scanning applies the acoustic radiation force to the subject so as to generate the shear waves, and each position within the third region is observed for a displacement based on the shear waves;
generate, based on a first color look-up table (LUT), a blood flow image in which a pixel value corresponding to the blood flow information is assigned to each pixel corresponding to the first region;
generate, based on a second color look-up table (LUT) that is different from the first color LUT, a tissue property image in which a pixel value corresponding to the tissue property information is assigned to each pixel corresponding to the third region;
generate a first superimposed image in which the blood flow image is superimposed on a morphologic image corresponding to the second region generated based on the morphology information;
generate a second superimposed image in which the tissue property image is superimposed on the morphologic image; and
display the first superimposed image, the second superimposed image, the first color LUT and the second color LUT side by side.
