Abstract

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).

Claims12

Dependent claims

An ultrasound diagnostic apparatus comprising:

a probe that transmits and receives ultrasound to and from a diagnosis region including a fetus;
a transmitting and receiving unit that obtains a reception signal of the ultrasound from the diagnosis region by controlling the probe;
a reference region setting unit that sets, in image data related to the diagnosis region obtained based on the reception signal, a body reference region for a body of the fetus and sets a cardiac reference region for a heart of the fetus;
a shift analysis unit that analyzes a motion of the body of the fetus using the body reference region in the image data to obtain shift information of the body;
a motion analysis unit that analyzes a motion of the heart of the fetus using the cardiac reference region in the image data to obtain motion information of the heart;
and
a pulse information processor that obtains pulse information of the fetus based on the motion information of the heart from which the shift information of the body is subtracted.
