摘要： After the establishment of the saturation state of a contrast medium which has flowed into a subject for photographing 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 photographing, 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.

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： An ultrasonic diagnosis apparatus sets transmission conditions that are different depending on a scanning direction so that a transmission sound field in a scanning region is uniform in a scanning of ultrasonic beams in one frame; transmits ultrasonic beams to a subject under the thus set transmission conditions; and samples a harmonics component from a ultrasonic echo signal reflected from a subject of the thus transmitted ultrasonic beams, thereby obtaining a harmonics ultrasonic image of the subject. According to this ultrasonic diagnosis apparatus, in the case of harmonics imaging as well, an entirely uniform image quality with less non-uniformity is achieved, and information useful for diagnosis can be provided on a clinical application site.
