Patent ID: 8167807

Claim:
An ultrasonic diagnosis device for measuring a motion parameter of a biological tissue on the basis of time-series ultrasonic image data collected by ultrasonic scanning on a sample and generating parameter image data on the basis of the motion parameter, the ultrasonic diagnosis device comprising: a motion parameter measuring unit measuring a motion parameter of the biological tissue on the basis of the ultrasonic image data; a parameter image data generating unit generating time-series parameter image data on the basis of the motion parameter; a heartbeat period setting unit setting the diastole and the systole of the biological tissue; a time phase setting unit setting a diastolic heartbeat time phase relative to the systole end of the biological tissue on the respective time-series parameter image data at least in the diastole of the ultrasonic image data; a heartbeat time phase setting unit setting a desired heartbeat time phase based on a ratio to the diastole; an image data extracting unit extracting the parameter image data at the diastolic heartbeat time phase corresponding to the desired heartbeat time phase; and a display unit displaying the extracted parameter image data.
