摘要： A method for assessing blood flow in a tissue involving directing a beam through the tissue along overlapping lines of sight and then generating the blood flow data from where the ultrasonic beams overlap to evaluate blood flow in the tissue. More specifically, spatially overlapping beams are generated at a fixed temporal intervals. Spatial overlap allows the spatial distance between overlapping lines-of-sight to be ignored, while moving reflectors within any overlapping line-of-sight will cause detectable changes in range of the moving reflector from one line-of-sight to the next. The rate of motion is determined from the measured change in range and the known time interval between vectors. Processing of data includes alignment of data between lines-of-sight to suppress artifactual motion and a wall filter for isolation of flow-data from stationary structures. An apparatus for assessing blood flow includes a transmission system and a storage system. The transmission system generates a beam which is sequentially transmitted towards the tissue along a plurality of overlapping lines of sight and receives echo data from the transmission along each of the lines of sight. The storage system stores the echo data.

摘要： A system and method for accumulating ultrasound information from a region of interest during a storage period are disclosed. The accumulated ultrasound information is then processed during a post-storage operation to provide a number of various and selectable analysis and display modes. Ultrasound echo signal data comprising, for example, a complete set of raw RF signal samples (or the quadrature signals I & Q) are accumulated in a cinescan memory during a storage period for multiple range positions along one or more scan lines covering a region of interest. Line interleaving and multi-line acquisition techniques may be employed in data accumulation. The accumulated echo signal data is processed during a post-storage operation to provide a number of various and selectable analysis and display modes. During the post-storage playback operation, any known signal processing and data manipulation techniques, which have conventionally been carried out in real-time during a scanning session, may be employed. The various known parameters of signal processing and data manipulation may be selectably modified during post-storage playback to optimize the displayed output. For example, in an off-line playback mode, the system operator may select any scan line and Doppler gate location and width within the region of interest for spectral Doppler analysis or for color M-mode analysis. The system operator may also manually set and reset one or more beam/vessel angles during the off-line playback mode to provide quantitative velocity color mapping. Other parameters such as spectrum scale, Doppler dynamic range, Doppler gain, baseline and color mapping may also be modified during off-line playback. Other known signal processing operations such as noise suppression, filtering, low intensity rejection and/or fixed target canceling may be performed, and the parameters thereof adjusted, during the post-storage operation.

摘要： Apparatus for mapping a surface of a cavity within a body of a subject includes an elongate probe, having a longitudinal axis and including a distal portion adapted for insertion into the cavity. A primary acoustic transducer on the distal portion of the probe is adapted to emit acoustic waves while the probe is in the cavity. A plurality of secondary acoustic transducers, distributed along the longitudinal axis over the distal portion of the probe, are adapted to receive the acoustic waves after reflection of the waves from the surface of the cavity and to generate, responsive to the received waves, electrical signals indicative of times of flight of the waves.

摘要： An ultrasonic imaging system uses a specially configured scanhead to provide ultrasound return signals that are processed by an imaging unit to generate a three-dimensional Doppler ultrasound image. One embodiment of the scanhead includes a first pair of apertures aligned along a first axis, and a second pair of apertures aligned along a second axis that is perpendicular to the first axis. All of the apertures lie in a common plane. Respective signals from the apertures along each axis are processed to generate two-dimensional Doppler motion vectors. The resulting pairs of two-dimensional Doppler motion vectors are then processed to generate three-dimensional Doppler motion vectors that are used to generate a three-dimensional Doppler image. In another embodiment, three co-planar apertures are arranged equidistantly from each other about a common center, and the three-dimensional Doppler image is generated from respective signals from the apertures.

摘要： A chord propagation velocity measurement (CPVM) system is used in connection with, for example, a brightness-mode (B-mode) or doppler ultrasound imaging system. The CPVM system monitors ultrasound data provided to it by the ultrasound imaging system and enhances the functionality of the ultrasound imaging system by providing a chord propagation velocity (CPV) associated with a body region, such as a blood vessel in a living thing. The CPV is indicative of the stiffness of the body region. In architecture, the CPVM system includes a tissue processor connected to the scanner of the ultrasound system designed to analyze each acoustic scan line and to determine a category (type of region, for example, blood or tissue) for each point along each acoustic scan line. A display produces an image generated from acoustic scan lines. A user input mechanism permits a user to identify a region of interest in the image. The tissue processor produces samples based upon the region of interest in the image. A CPV determination system, which is connected to the tissue processor, acquires a plurality of the samples from different subregions along a longitudinal span of the region for each of a plurality of different cycles, derives a plurality of composites, one for each subregion, by combining corresponding samples from different cycles, and produces a CPV based upon the plurality of composites. Preferably, the CPV is displayed, printed, or otherwise output by the CPVM system to the user of the ultrasound imaging system in real time to permit immediate analysis, and evaluation of the body region by the user.

摘要： Methods, systems and devices are provided for monitoring and quantifying the movement of fluid in a target region. Generally, an imaging agent is introduced into a target region through fluid flow. The imaging agent in the target region is then disrupted using appropriate methods such as the application of ultrasonic energy. As fluid flow brings undisrupted imaging agent into the target region, the rate of accumulation is monitored and quantified thereby providing the exchange rate and flow rate of the fluid in the target region. The disclosed invention is particularly useful for medical applications such as determining the flow rate of blood in an organ or tissue.
