Abstract: The present invention relates to a system for forming 3-dimensional images, including: an image data forming unit for forming 3-dimensional volume data based on image signals; an image forming unit for forming multiple sectional plane images sliced along a predetermined direction in a 3-dimensional image, the image forming unit being configured to form at least one 3-dimensional image with partial 3-dimensional volume data selected by using the multiple sectional plane images from the 3-dimensional volume data; and a displaying unit for displaying the multiple sectional plane images and the 3-dimensional image.

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

Abstract: A memory cell structure includes non-volatile as well as SRAM memory cells that share the same bitline and operate differentially. The SRAM cell includes first and second MOS transistors that are coupled to the same true and complementary bit lines that the non-volatile memory cells are coupled to. The non-volatile memory cells are erased prior to being programmed. Programming of the non-volatile memory cells may be carried out via hot-electron injection or Fowler-Nordheim tunneling. Data stored in the non-volatile memory cells may be transferred to the SRAM cell. The differential reading and writing of data reduces over-erase of the non-volatile devices.

Abstract: The present invention relates to a rendering apparatus and method for a real-time 3D ultrasound diagnostic system, which can improve both the speed of rendering in a real-time manner 3D ultrasonic images and 2D ultrasonic images therefrom, based on the view operation for displaying ultrasonic images for a target object and the speed of scanning and converting 3D data.

Abstract: An apparatus for displaying sectional planes of a target object utilizing 3 dimensional (3D) ultrasound data. The apparatus is capable of scanning the target object in real time by improving a scan conversion speed and virtually scans the target object by storing previously acquired 3D data. The apparatus, which displays a target object by using 3D ultrasound data, includes 1) a scan conversion unit for performing scan conversion to convert Cartesian coordinates for display on a screen of a display device to conical coordinates of 3D data, and 2) a rendering unit for rendering multiple sectional plane images, based on the 3D scan conversion, parallel with a reference sectional plane.
