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： 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.

摘要： In a high-resolution flow mode, a diagnostic ultrasound apparatus and a diagnostic ultrasound method that provide an image of blood flow or perfusion is provided with higher sensitivity and high resolution, which makes it possible to precisely observe the presence of fine blood vessels. In this apparatus, by scanning means (81 to 83), with a ultrasound pulse having a wideband frequency characteristic transmitting at least two times in the same direction within an object, a cross section to be imaged therein is scanned to obtain an echo signal at each time of transmission. By processing means 84, highpass filtering or differential processing is performed with rows of data in the time axis direction of an echo signal acquired at each sample location in the cross section, so that signals from blood flow are extracted. By producing means 85, the processed signals are produced into data of luminance or power. This data is displayed by displaying means 86 as a high-resolution color (flow) image or grayscale flow image indicative of blood flow or perfusion.

摘要： According to one embodiment, an ultrasonic diagnosis apparatus executes B-mode scanning and color Doppler mode scanning on a scanning region associated with an interior of the womb of a pregnant woman via an ultrasonic probe. A first generating unit generates first color Doppler mode data and generates first B-mode data. A specifying unit specifies a specific region including at least one of an amniotic fluid region and a fetus region based on one of a signal intensity distribution and a luminance distribution of the first B-mode data. A second generating unit generates second color Doppler mode data by deleting a specific data from the first color Doppler mode data. The specific color Doppler mode data corresponds to the specific region. A display unit displays a color Doppler mode image and a first B-mode image while superimposing the color Doppler mode image and the first B-mode image.

摘要： There is provided an ultrasonic wave diagnosis instrument. The ultrasonic wave Doppler diagnosis instrument transmits an ultrasonic continuous wave in a range direction and receives a reflective wave of the ultrasonic continuous wave. The ultrasonic wave Doppler diagnosis instrument includes: a modulation unit that subjects the ultrasonic continuous wave to frequency modulation such that a phase is varied in accordance with the distance of the range direction; a demodulation unit that demodulates the reflective wave for each range of the range direction while interlocking with the frequency modulation, and generates a reception signal in the range in a separated state; and a presentation unit that presents information by using a signal of a Doppler component based on the reception signal.
