摘要： In tomographic image data, a reference region-setting unit (30) sets a body reference region for the body of a fetus and sets a cardiac reference region for the heart of the fetus. A body shift analysis unit (50) analyzes the movement of the fetus' body in the tomographic image data using the body reference region and obtains body shift information. A cardiac motion analysis unit (60) analyzes the movement of the fetus' heart in the tomographic image data using the cardiac reference region and obtains cardiac motion information. Once body shift information and cardiac motion information are obtained in this manner, a pulse information-processing unit (70) obtains fetal pulse information on the basis of the cardiac motion information from which the body shift information has been subtracted. The pulse information obtained by the pulse information-processing unit (70) is displayed on the display unit (80).

摘要： An ultrasonic diagnostic apparatus which can measure a time difference of motion between a plurality of sites of a cardiac muscle for the heart of a fetus is provided. On a tomographic image of the heart, a user sets a plurality of observation points. Each observation point is tracked, and a plurality of displacement waveforms representing a temporal displacement of the plurality of observation points are generated. A time difference between a plurality of representative points is calculated between the plurality of displacement waveforms. Such a time difference is displayed as a numerical value or as a graph. The representative point is a peak point, a zero-cross point, an inflection point, or the like. The plurality of observation points are set along conduction pathways in the heart for the electric signal.
