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： Systems and methods for determining circumference and a percent change in circumference of a structure are provided. Certain methods include receiving first and second sets of at least three vertical plane images of a structure about a long axis of the structure that were acquired at first and second points in time, respectively. Data points from each of the images of each of the sets that define a contour of the structure are identified. The circumference of the structure at a horizontal plane of the structure at the first and second points in time using identified data points positioned on the horizontal plane is estimated. A percent change between the estimated circumference of the structure at the first point in time and the estimated circumference of the structure at the second point in time is determined.

摘要： Method and apparatus for assessing tissue motion and deformation is provided. Sequential frames of data representative of tissue are accessed. A region of interest is defined on a current frame of data, and first locations of a set of features within the region of interest is identified. Each feature in the set of features identifies a location within the tissue. Second locations of the set of features are located on a consecutive frame of data. Velocity vectors are calculated based on the first and second locations of the set of features, and a continuous spatial and temporal velocity distribution is reconstructed by fitting the velocity vectors.
