Abstract
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 of…
