Abstract:
An ultrasound diagnostic apparatus comprising:a 2D array ultrasound probe having a plurality of transducer elements arranged as a matrix array;a transmitting unit for supplying a high-frequency signal to the transducer element so as to transmit an ultrasound beam to a human subject;a receiving unit for forming a received signal of a receiving directivity from an echo signal received at the respective transducer element;a delay control unit for controlling the transmitting and receiving units so as to scan a three-dimensional region of interest in the human subject;a filter for extracting harmonic components from the received signals formed by the receiving unit in real time; anda processor for, based on the extracted harmonic components, creating a three-dimensional image relating to the three-dimensional region of interest in real time;wherein the receiving unit forms a plurality of received signals of different receiving directivities after one transmission and the transmitting unit simultaneously transmits a plurality of ultrasound beams of different transmitting directivities.
