摘要： An ultrasound diagnosis system, a medical image display apparatus and displaying method that simultaneously acquires virtual endoscopy image data and multi-planar-reconstruction (MPR) image data of a diagnosing target region based on the volume data acquired from an object. Virtual endoscopy image data is generated by setting up a viewing point and a viewing direction on a volume data acquired from the object. A marker is provided on a target region of a lumen organ shown in the virtual endoscopy image data for setting up an observing direction. A reference line started from the volume data is set up along an observing direction. By comparing a voxel value of the volume data that is crossing to the reference line with a prescribed threshold value, a reference point where a surface of the diagnosing target region crosses the reference line is set up to the volume data. MPR image data is generated by extracting each voxel of the volume data corresponded to each of three MPR cross-sectional planes that are mutually orthogonally crossing at the reference point and displayed with the virtual endoscopy image data.

摘要： According to one embodiment, a gain adjustment unit executes gain adjustment for 3D B-mode data using gain adjustment values respectively decided for the depth on each scanning line, azimuth direction and elevation direction in a scanned region. A threshold decision unit decides a threshold used for discriminating lumen and non-lumen regions in the scanned region using the gain-adjustment-executed 3D B-mode data. A threshold processing unit executes threshold processing to discriminate data concerning the non-lumen region from the gain-adjustment-executed 3D B-mode data, using the threshold. An image generation unit generates an ultrasonic image concerning the lumen region based on the threshold-processing-executed 3D B-mode data.

摘要： An ultrasound imaging apparatus and method in which an ultrasound signal is transmitted a plurality of times in each scanning direction and its echo is received. A Doppler signal detected from a group of echo signals consisting of a train of sequential Doppler data for each spatial sample position in each scanning direction. The amount of instantaneous changes in a phase of a clutter component included in the Doppler signal is estimated, the clutter component occurring due to reflection of the ultrasound signal from an organ. A phase of the Doppler signal is corrected using the estimated amount of instantaneous changes in the phase. A constant value corresponding to the clutter component is subtracted from the Doppler signal of which phase is corrected, information representing a blood flow is extracted based on the Doppler signal of which clutter component is removed and the extracted information is displayed in color.

摘要： A diagnostic ultrasound apparatus is provided for obtaining an image of an object into which an ultrasound contrast agent is injected. The apparatus has a transducer 1 for transmitting and receiving an ultrasound wave to and from the object and transmitting means (2, 81, 83) transmitting an ultrasound pulse into the object by driving the transducer under a first transmitting condition exerting a given destruction capability on the ultrasound contrast agent and a second transmitting condition having a destruction capability lower than that of the first condition. First image producing (3, 5) receive an ultrasound echo of the ultrasound pulse transmitted under the first transmitting condition and produce a first color-displayed image based on phase displacement information about the ultrasound echo. Additionally, second image producing means (3, 4) receive an ultrasound echo of the transmitted ultrasound pulse and produce a second image based on amplitude information about the ultrasound echo. The first and second images are displayed by display means (6, 82). According to this diagnostic ultrasound apparatus, for imaging a CFM image based on a flash echo phenomenon caused in an object in which a contrast agent injected, one interval during which the phenomenon will be caused and the other interval during which it will not be caused can be determined appropriately and images can be displayed effectively over those intervals.
