    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.

    摘要： The present invention relates to a stereoscopic imaging apparatus (2). The apparatus (2) comprises a real time ultrasound imaging device (14, 20, 22) for generating a real time 3D model of a patient's heart (4), combining the real time 3D model with a static 3D model of the region surrounding the heart (4) previously stored in memory (24), and generating stereoscopic image data of the combined real time and static 3D model. The apparatus also comprises a display (30) for simultaneously displaying the real time stereoscopic image of the heart (4) and a static stereoscopic image of the region surrounding the heart (4). By enabling a real time stereoscopic image of the heart (4) and a static stereoscopic image of the region surrounding the heart to be simultaneously displayed on the display (30), this improves the user's depth perception in viewing the real time image.

    摘要： Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.
