摘要： The difference frequency component between a first fundamental wave of frequency f and a second fundamental wave of frequency f2 is caused to interact with a second harmonic wave, thereby to attain the enhancement of a second harmonic signal, etc., whereby a reflected wave component to be imaged is extracted at a high S/N ratio. By way of example, in a case where the difference frequency component is to appear on the lower frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=2.8 f or so. Besides, in a case where the difference frequency component is to appear on the higher frequency side of the second harmonic wave of the first fundamental wave so as to be superposed on this second harmonic wave, the frequencies are set at f2=3.2 f or so.

摘要： In time phases except a first time phase, a contour tracking part tracks the position of a region of interest based on image data acquired in each of the time phases. A re-tracking part receives correction of the position of the region of interest in a second time phase, and obtains the position of the corrected region of interest in and after the second time phase based on the image data acquired in and after the second time phase. From position information of the region of interest in and before the second time phase and position information of the corrected region of interest in and after the second time phase, a position calculator obtains position information of the region of interest in all the time phases. A computing part obtains motion information of a tissue within the region of interest based on the position information of the region of interest.
