Ultrasonic diagnosis apparatus
An ultrasonic diagnosis apparatus is provided. The ultrasonic diagnosis apparatus includes an ultrasonic probe configured to transmit ultrasonic push pulses to a biological tissue of a test object and further configured to transmit measuring ultrasonic pulses to the biological tissue subjected to the transmitted push pulses in order to measure an elasticity of the biological tissue, a respiration detection part configured to detect respiration of the test object, and a notification part which, based on the detection by the respiration detection part, is configured to give notification allowing a transmission timing of the push pulses to be recognized.
1. An ultrasonic diagnosis apparatus comprising:
an ultrasonic probe; and
a processor configured to:
control the ultrasonic probe to transmit ultrasonic pulses for detecting a movement of a biological tissue caused by a heartbeat or respiration;
execute a first program to implement a movement detection function for detecting the movement of the biological tissue based on echo data from the ultrasonic pulses for detecting the movement of the biological tissue, where detecting the movement includes detecting a displacement of the biological tissue;
execute a second program to determine a time period when the displacement of the biological tissue is less than a threshold value after detecting the movement of the biological tissue;
control the ultrasonic probe to transmit ultrasonic push pulses during the time period when the movement of the biological tissue is less than the threshold value; and
control the ultrasonic probe to transmit measuring ultrasonic pulses to the biological tissue after transmitting the ultrasonic push pulses, where the measuring ultrasonic pulses are adapted to detect a propagation velocity of a shear wave generated in the biological tissue by the ultrasonic push pulses.
2. An ultrasonic diagnosis apparatus according to claim 1 , wherein the processor is further configured to display a first image showing a chronological change in the movement of the biological tissue.
3. An ultrasonic diagnosis apparatus according to claim 2 , wherein the processor is further configured to display a second image indicating the transmission timing of the push pulses.
4. An ultrasonic diagnosis apparatus according to claim 1 , wherein the processor is further configured to output a sound indicating that it is time to transmit the ultrasonic push pulses based on the detected displacement of the biological tissue with respect to the threshold value.
5. The ultrasonic diagnosis apparatus of claim 1 , wherein the processor is configured to automatically control the ultrasonic probe to transmit the ultrasonic push pulses during the time period when the movement of the biological tissue is less than the threshold value.
