  • Publication number: 20070053566
    Abstract: The present invention relates to an apparatus for processing an ultrasound image of a target object including a periodically moving object, including: an ROI setting unit for setting regions of interest (ROIs) to each of frames constituting ultrasound volume data acquired from a target object; a VOI setting unit for selecting a predetermined number of first reference frames from the ultrasound volume data and setting a predetermined number of volumes of interest (VOIs) by combining ROIs of the first reference frames with ROIs of frames adjacent to the reference frames; a motion compensating unit for processing the VOIs to compensate a motion of the target object; a correlation coefficient curve calculating unit for calculating a correlation coefficient curve for a predetermined interval at each VOI; a period setting unit for setting a moving period of the moving object based on the correlation coefficient curve in the volume data; and an ultrasound volume data reconstructing unit for reconstructing the ultras

  • Publication number: 20070038106
    Abstract: The present invention relates to an ultrasound diagnostic system and method for automatically controlling the brightness and contrast of a three-dimensional (3D) ultrasound image. The method for automatically controlling the brightness and contrast of a 3D ultrasound image includes the steps of: creating 3D ultrasound image data based on ultrasound echo signals; setting a critical value for rendering the 3D ultrasound image data; rendering the 3D ultrasound image data by using the critical value to form a 3D ultrasound image; analyzing a histogram of the 3D ultrasound image to set image parameters for the 3D ultrasound image; and adjusting the brightness and contrast of the 3D ultrasound image based on the image parameters.

  • Publication number: 20060003266
    Abstract: The present invention relates to an organic electroluminescence display and a fabricating method thereof enabling to simplify a manufacturing process and reduce a product cost by separating devices with a single insulating pattern. The present invention includes the steps of: forming a plurality of stripe type first electrodes on a substrate; forming an insulating layer on the substrate including the first electrodes; forming a lattice type first insulating pattern on a first area crossing with the first electrodes and a second area between the first electrodes by patterning the insulating layer; forming a second insulating pattern by removing an upper portion of a part of the first insulating pattern on the first area at least and an upper portion of the first insulating pattern on the second area; forming organic light-emitting layers on the first electrodes; and forming a plurality of second electrodes on the organic light-emitting layers.

  • Publication number: 20050214195
    Abstract: A method for forming CNT multilayer film patterns, which comprises repeatedly attaching CNTs having exposed carboxyl groups onto a substrate having exposed amine groups by amide linkage, so as to form a CNT multilayer film, and then forming CNT multilayer film patterns from the CNT multilayer film by photolithography and dry etching. Also disclosed is a method for fabricating CNT multilayer film patterns where a variety of chemical functional groups are exposed, by thermally treating CNT multilayer film patterns obtained as provided in the preceding sentence, to obtain CNT multilayer film patterns devoid of surface defect sites, followed by physically attaching either surfactants or chemical substances having sites capable of ?-stacking, to the CNT multilayer film patterns devoid of defect sites. Such methodology allows fabrication of clear CNT multilayer film patterns in which CNTs are attached only at selected regions, resolving prior art issues of CNTs being attached also at non-selected regions.
