The ultrasound echo data has one of local single octant spectra, local single quadrant spectra, and local single half-band-sided spectra in a frequency domain. The ultrasound echo data is obtained from plural same bandwidth spectra. A data processing unit calculates a displacement at each local position or distribution thereof in at least one of axial, lateral, and elevational directions by solving simultaneous equations derived at each local position via implementing a predetermined displacement measurement method on the ultrasound echo data yielded at the plural different temporal phases with respect to at least one of the axial, lateral, and elevational carrier frequencies and the phase, or the one of the local single octant spectra, the local single quadrant spectra, and the local single half-band-sided spectra.

In a medical diagnostic imaging system, a method for adjusting image gain compensation during a transition from a first imaging state to a second imaging state, including the steps of determining a first image power value based an image acquired in a first imaging state with a first image gain compensation; determining a second image power value based on an image acquired in a second imaging state with an initial second image gain compensation; determining an image power change value based on the first image power value and the second image power value; and determining an adjusted second image gain compensation based on the initial second image gain compensation and the image power change value.

The ultrasonic diagnostic system estimates a desired time phase or one cycle period of a moving region (e.g., a heart) that repeats contraction and relaxation cyclically and which can be specified by a presystole, an end systole, a prediastole, an end diastole, and other clinical characteristics for one cycle of the moving region on the basis of the velocity information on multiple positions of the moving region which is obtained for each time phase. More specifically, assuming that, for example, the end systole phase=a time phase in which the myocardial velocity comes to zero or close to zero, the system calculates |myocardial velocity| for each time phase in a predetermined period, and estimates a time phase in which this value comes closest to zero as an end systole phase.

An ultrasound diagnostic apparatus which includes: an imaging unit which forms images of a subject; a motion detection region setting unit which selects a first image from among the images which include images of the ultrasound contrast agent, selects a second image from among the images which do not include images of the ultrasound contrast agent, and sets, as a motion detection region, a region in which an amount of image change between the first image and the second image is smaller than a predetermined amount; and an output unit which outputs, as the ultrasound diagnostic image, the second image on which a position adjustment has been performed to match a position of the motion detection region set by the motion detection region setting unit and a position of a region included in the second image and similar in an image feature to the motion detection region.

An ultrasound diagnosis apparatus includes a transmitting and receiving circuitry, an input circuitry, and a processing circuitry. The transmitting and receiving circuitry transmits a first ultrasound wave used for changing the shape of a tissue in the body of a patient and transmits/receives a second ultrasound wave that is transmitted/received with timing different from that of the first ultrasound wave. The input circuitry receives an input of a request indicating that the first ultrasound wave should be transmitted. When the input circuitry has received the input of the request indicating that the first ultrasound wave should be transmitted, the processing circuitry controls the transmission of the first ultrasound wave in accordance with the strength of a reflected-wave signal of the second ultrasound wave or one or more pixel values of an image resulting from an imaging process performed by using the reflected-wave signal of the second ultrasound wave.
