摘要： A region-of-interest setting unit sets a region of interest to be included in an ultrasound image. A first movement-amount calculating unit sequentially calculates a movement amount of the set region of interest between reception data along the time sequence as a first movement amount. A transmitting-receiving delay-amount computing unit computes a delay amount for sequentially shifting a scan region of an ultrasonic beam based on the sequentially calculated first movement amount. A computation/control circuit performs control so as to generate a high voltage pulse based on the computed delay amount. A second movement-amount calculating unit sequentially calculates a movement amount of the region of interest between image data along the time sequence as a second movement amount. A display-position correcting unit performs a correction such that the region of interest included in the image data is to be displayed at the same display position, based on the second movement amount.

摘要： With respect to a scanning plane of a subject having been injected with a contrast agent, an ultrasound transmission section 6 transmits for a plurality of times an ultrasonic pulse of such an intensity capable of collapsing the contrast agent. An ultrasound reception section 5 receives an echo signal cluster from the subject based on the ultrasonic pulses, and generates a plurality of RF data items through addition of the echo signal cluster using an adder 5C. Based on the plurality of RF data items, a TIC/MTT measurement section 25 measures a time intensity curve (TIC), and then measures a mean transit time (MTT) of the blood flow based on the time intensity curve for display on a display section 21.

摘要： After the establishment of the saturation state of a contrast medium which has flowed into a subject for scanning inside a patient given the contrast medium, scan is performed under a high acoustic pressure adapted to break the bubbles of the contrast medium, so as to refresh the section for the scanning, and to acquire the maximum value of echo signal intensities. Subsequently, scans by ultrasounds under a low acoustic pressure or a medium acoustic pressure which does not break the contrast medium are carried out a plurality of times at different timings, thereby to execute a scan sequence for acquiring in-vivo information necessary for a TIC analysis. Data obtained by the scans are analyzed in a blood-flow-index estimation unit, and are displayed in a predetermined scheme.
