  • Publication number: 20110087102
    Abstract: 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.

  • Publication number: 20100222680
    Abstract: An image-manipulation receiving unit receives an image manipulation by a user. A viewpoint/mark calculating unit calculates a viewpoint and a display position of a probe mark based on the image manipulation by the user. A mark-notation creating unit creates a probe mark, a front-back distinction mark, a line of indicating position just beneath probe center, a line of indicating scan area, and a quadrangular pyramid mark, as a mark. An image compositing unit then composites a color Doppler image with the marks, and displays them onto a monitor.

  • Patent number: 7776305
    Abstract: A nitrogen oxide purifying apparatus includes a gas absorption vessel (1) and a condenser (6), where the vessel receives an absorption solution containing liquefied N2O4 for absorbing NO and also receives a source gas to vary the temperature and/or pressure of the source gas and the absorption solution, while the condenser receives a gas from the gas absorption vessel (1) to vary the temperature and/or pressure of the gas. In the gas absorption vessel (1), the absorption solution containing liquefied N2O4 may be applied to the source gas containing NO, so that NO is absorbed in the absorption solution. Then the absorption-solution is heated and/or depressurized to generate an intermediate gas containing a relatively large amount of NO and a smaller amount of NO2 from the absorption solution. In the condenser (6), the intermediate gas is cooled and/or pressurized to give condensed N2O3 and/or condensed N2O4.

  • Publication number: 20100185094
    Abstract: 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.

  • Patent number: 7709146
    Abstract: Disclosed are a bipolar battery, a bipolar battery component and a method of manufacturing the same. The bipolar battery minimizes the occurrence of gas bubbles to provide superior battery performance. A battery element has a plurality of bipolar electrodes stacked upon one another while interposing separators therebetween. The bipolar electrode includes a collector formed with a cathode on one surface and an anode on the other surface. The component is a charging part with charging material disposed between collectors and separators to surround at least a periphery of the cathode and a periphery of the anode. An exhaust part is mounted to the charging part to exhaust a residual gas bubble from an inner space to outside of the inner space when stacking the bipolar electrodes.

  • Publication number: 20100099987
    Abstract: Volume data are collected by swing scanning in which frames in different field angle settings are mixed by a wide scan set at a wide field angle to image a diagnostic target and an index part for recognizing the position of the diagnostic target and by a narrow scan set at a field angle ?2 narrower than the field angle in the wide scan to image the diagnostic target with high time resolution. Then, the wide ultrasonic image is used to set spatial coordinates based on the index part. The spatial coordinates are used to align the narrow ultrasonic image. While this positional relation is being maintained, the wide ultrasonic image, the narrow ultrasonic image and a given ultrasonic image are displayed in a predetermined form.

  • Publication number: 20100030079
    Abstract: An ultrasound imaging apparatus capable of easily displaying a three-dimensional image included in a region of interest (ROI) is provided. A display controller 9 causes a display 10 to display a tomographic image, and further causes the display 10 to display a first marker indicating a three-dimensional scan range and a second marker indicating a range to generate three-dimensional image data (a range subjected to rendering) so as to be superimposed on a tomographic image. The second marker is rotatable on the tomographic image in accordance with an instruction by an operator. A transceiver 3 causes an ultrasound probe 2 to scan the three-dimensional scan range specified based on the first marker. An image processor 7 executes rendering on, of data acquired in the scan, data included in the range specified based on the second marker, thereby generating three-dimensional image data.

  • Publication number: 20090082668
    Abstract: An imaging part transmits ultrasonic waves to a specific tissue having a tubular morphology in a three-dimensional region and acquires volume data showing the specific tissue. A tomographic image generator generates tomographic image data in a specified cross-section of the specific tissue based on the volume data. A boundary setting part sets a boundary of the specific tissue shown in the tomographic image data. A developed image generator sets a viewpoint at a specified position with respect to the boundary and executes a rendering process on the volume data along a view direction from the viewpoint toward the boundary, thereby generating developed image data in which the specific tissue is developed along the boundary. A display controller controls a display to display a developed image based on the developed image data.
