1. An ultrasound diagnostic apparatus comprising:
transmission circuitry configured to repeat a plurality of ultrasonic wave transmissions with different transmission angles and/or different transmission origins in units of packets by way of an ultrasonic probe including a plurality of transducers;
reception circuitry configured to receive a plurality of reception signals corresponding to the ultrasonic wave transmissions by way of the ultrasonic probe;
beamforming circuitry configured to perform beamforming respectively on the reception signals and generate a plurality of initial images;
filtering circuitry configured to perform MTI filtering on the initial images for each group of the same transmission angle and/or the same transmission origin and generate a plurality of MTI images;
principal component analysis circuitry configured to perform a principal component analysis on the MTI images for each of the packets having the same set of transmission angles and/or the same set of transmission origins and generate a plurality of principal component images; and
coherent addition circuitry configured to perform coherent addition on the principal component images for each of the packets and generate a plurality of coherent addition images.
