摘要： In transmissions of each frame through intermittent transmissions, by performing ultrasonic wave transmissions while increasing a mechanical function step by step, destructions of bubbles of a contrast medium can be induced step by step according to their different sizes. By generating ultrasonic images using the destructions at the respective steps as the sources of echoes, it is possible to provide new ecological information including, for example, information reflecting the dynamics of substances smaller than the red blood cells, the distribution of predatory cells, new diagnosis information, etc.

摘要： An ultrasonic diagnostic apparatus comprises a unit for generating image data, an image reconstructing unit and an image synthesizing unit. The unit for generating image data generates image data for displaying a tomogram of a subject by luminance according to signal intensities of echo signals obtained through ultrasonic waves transmitted to the subject. The image reconstructing unit generates reconstructed images by alternating at least one of a luminance and a color of an area of a predetermined luminance so that the area of the predetermined luminance is emphasized in the image data while the predetermined luminance is altered in turn. The image synthesizing unit supplies the reconstructed images to a display unit so that the reconstructed images are displayed on the display unit in turn.

摘要： In ultrasound diagnosis, a contrast echo technique on three-dimensional scanning is used with a contrast agent injected into an object. Before injecting the contrast agent and under the injection thereof, a blood vessel is continuously and securely targeted and depicted in displayed images. To realize this, a diagnostic ultrasound apparatus has means for acquiring an echo signal by scanning a three-dimensional region of an object with an ultrasound beam, means for producing three-dimensional image data based on the echo signal, means for displaying the three-dimensional image data, means for specifying, for example, from the echo signal, a timing at which injecting an ultrasound contrast agent into a region to be scanned of the object is started, and means for switching over at the specified timing display states of the three-dimensional image data to be displayed by the displaying means. By way of example, the switchovers are carried out such that data produced by projecting the three-dimensional image data on a minimum intensity projection technique are displayed before injecting the contrast agent, while data produced by projecting them on a maximum intensity projection technique are displayed after the start of injecting the contrast agent.

摘要： An ultrasonic diagnostic apparatus includes an ultrasound probe, a transmitting device, a receiving device, a transmission control circuit, and an image generating unit. The transmission control circuit controls the transmitting device, so that an imaging region of a subject is scanned throughout with ultrasound during a scanning operation. The scanning operation is repeated, and ultrasound for collapsing micro-bubbles administered to the subject is transmitted in an interval between scanning operations. In a region where the ultrasound for collapsing micro-bubbles is transmitted, a greater number of micro-bubbles collapse than in the other region where the ultrasound for collapsing micro-bubbles is not transmitted. Accordingly, the contrast effect is partially reduced in the imaging region. Therefore, image data has a portion of a higher contrast effect and a portion of a lower contrast effect.

摘要： In performing harmonic echo imaging, the necessity of changing modes is obviated, maneuverability is improved, and diagnostic information of the kinetics of a blood flow is provided with high reliability. A diagnostic ultrasound system provides, by scanning a cross section of an object with an ultrasonic beam signal, a normal B-mode image (the first tomographic image) of a tissue and a harmonic-mode image (the second tomographic image) of distribution information of an ultrasonic contrast medium injected into the object. The distribution information is obtained based on a non-fundamental frequency component (e.g., second harmonics) other than a fundamental frequency component of the ultrasonic beam signal. The system comprises a unit for scanning an ultrasonic beam signal along the cross section to acquire an echo. The scanning unit controls the scan so that the beam signal is scanned automatically and alternately for each raster in both the normal B-mode and the harmonic-mode. Preferably, the scan in the harmonic-mode precedes that of the normal B-mode. Image data of the first and second tomographic images are visualized on the basis of the echo.

摘要： An ultrasonic diagnostic apparatus that performs high acoustic pressure and low acoustic pressure ultrasonic transmissions by switching at predetermined timing in the enhanced ultrasonography, and displays concurrently a replenishment image obtained through the low acoustic pressure transmission in real time like a moving picture, and a pre-flash image obtained through the low acoustic pressure transmission immediately before switching to the high acoustic pressure transmission like a still image to allow the operator to understand the structure at the level of capillaries. It is also possible to display a selected image obtained through the low acoustic pressure transmission at an arbitrary timing instead of the pre-flash image.
