摘要： In the event that images are acquired for multiple cross-sections (multiple phases) by a predetermined imaging mode in an examination under stress to a subject, images of the same phase acquired by the same imaging mode in an examination before stress to the subject is read and simultaneously displayed as reference images together with current images. The operator can bring the cross-sectional position in the examination under stress in correspondence to the position of the examination before stress by comparing the displayed reference images with the current image.

摘要： An ultrasonic diagnostic apparatus transmits ultrasonic pulses relevant to each scanning line twice, for example, while changing a center frequency of a bandwidth; acquires an electrical receiving signal that corresponds to an ultrasonic echo for such each transmission; applies filter processing with characteristics in accordance with a bandwidth of a harmonic component of a respective one of two receiving signals received for each scanning line; synthesizes the thus processed two receiving signals; and generates/displays an image by using the synthesized receiving signal. In this manner, the resolution and signal intensity in a depth direction is improved by broadening the bandwidth of a harmonic component provided for image generation, and a harmonic image having an occurrence of a motion artifact restrained is provided.

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： A combined wave having a plurality of frequencies and phases is transmitted to each of a plurality of scan lines in at least three rates by alternately inverting a phase by 180°. An obtained echo signal is received for each rate. The echo signals are added by using arbitrary weighting coefficients so that 0 is obtained by using the polarity as the sign. Ultrasonic image data is generated by using a difference tone component contained in the added echo signal.

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=2.8f 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=3.2f or so.

摘要： An ultrasonic imaging apparatus comprises an ultrasonic probe, an image-processing part, a received signal intensity-adjusting part, and a display part. The ultrasonic probe three-dimensionally transmits/receives ultrasonic waves. The image-processing part generates a first ultrasonic image along a plane intersecting the scanning lines of ultrasonic waves, based on the signals obtained by transmitting/receiving of the ultrasonic waves. The signal intensity-adjusting part changes the intensity of the signals on the scanning lines passing through a brightness adjustment range for brightness adjustment set on the first ultrasonic image. The image-processing part generates a second ultrasonic image, based on the signal changed by the signal intensity-adjusting part. The display part displays the second ultrasonic image.
