    摘要： An improved imaging system includes a memory-storage unit, a multiple-dimensional image processor configured to convert information within a multiple-dimensional data set to a two-dimensional representation in a plane orthogonal to an operator-identified view axis, and an image-rendering device configured to display the two-dimensional representation of a volume-of-interest contained within the three-dimensional data set, wherein the two-dimensional representation is responsive to pixel values associated with a faceplate orthogonal to the view axis. A method for viewing information includes identifying a view axis that intersects a multiple-dimensional data set, modifying the multiple-dimensional data set to align the multiple-dimension data set responsive to the view axis, locating a portion of a structure-of-interest along a vector parallel to view axis, associating a set of pixels with a faceplate, and generating a composite view in accordance with the faceplate.

    摘要： A data management framework for a data communications network. The framework includes a dynamically constructed model of elements of the data communications network. The elements are represented as object instances that are self-descriptive. The model provides a uniform application programming interface that allows a client to dynamically access the elements and dynamically add new elements in performing network management functions. The data management framework may be used for policy management.

    摘要： An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region which are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce a “thick slice” image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. Thick slice images are displayed at a high frame rate of display by combining a newly acquired slice with slices previously acquired from different elevational planes which were used in a previous combination. A new thick slice image may be produced each time at least one of the slice images is updated by a newly acquired slice. Frame rate is further improved by multiline acquisition of the slices.

    摘要： A three-dimensional ultrasound imaging system color user interface generates a volumetrically-rendered ultrasound image. The ultrasound image is manipulable using three-dimensional image compositing functions. The interface presents to the user three-dimensional image controls for controlling the ultrasound image. The three-dimensional image controls have an operational similarity to two-dimensional image controls for controlling a two-dimensional ultrasound image. The interface further relates the three-dimensional ultrasound image controls to the plurality of three-dimensional image compositing functions for manipulating the ultrasound images. Additionally, the interface presents to the user a three-dimensional color image control for controllably manipulating the ultrasound image using three-dimensional image using compositing functions such as a color flow mapping function, a color flow overlay function for mapping fluid flow direction, a depth-based velocity visualization color mapping function; and an absolute velocity representation function for mapping absolute fluid flow velocity relating to said ultrasound object.

    摘要： An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a mitral valve. A flow quantification processor (34) in the ultrasound system produces a mathematical model of a flow velocity field proximal to a regurgitant orifice. The velocity field model produces values of velocity vectors directed toward the regurgitant orifice. These modeled values are modified for the effects of ultrasound physics and ultrasound system operation to produce expected velocity values. The expected velocity values are compared with actual Doppler velocities measured by the ultrasound system, and the differences accumulated to a mean square error which is used to adjust parameters of the model such as the orifice location and flow velocities. When this iterative processing converges with a desired comparison, parameters derived from the finally adjusted model are used to calculate the true orifice location, flow rate, and volume flow.

    摘要： An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region containing tissue which has been perfused by a contrast agent. The plurality of slices scanned are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce an elevationally combined slice image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. The elevationally combined slice image is processed to produce a qualitative or quantitative measure of perfusion, such as an image with degrees of perfusion indicated by a range of brightness levels, an image of color perfusion parameters, or a perfusion curve or curve parameter indicating rate of perfusion.
