Abstract:
An ultrasonic diagnostic apparatus comprising:an ultrasound probe;a transmitting device for driving the ultrasound probe to transmit ultrasound to a subject injected with micro-bubbles;a transmission control circuit for controlling the transmitting device to scan throughout an imaging region of the subject with ultrasound for imaging during a scanning operation, the scanning operation being repeated, and ultrasound for collapsing the micro-bubbles being transmitted in an interval between scanning operations;a receiving device for receiving echoes reflected by the subject during the scanning operation through the ultrasound probe;a unit for producing image data relating to the imaging region based on the received echoes; anda processor for generating a curve representing correlation between an interval from an end of transmission of the ultrasound for collapsing the micro-bubbles to a start of the scanning operation and brightness of a place where the ultrasound for collapsing the micro-bubbles is transmitted;wherein an interval from the end of transmission of the ultrasound for collapsing the micro-bubbles to the start of the scanning operation is changed in every scanning operation.
