Ultrasound system for generating a single set of ultrasound pulse firings
View Patent ↗An ultrasound imaging system configured to simultaneously acquire and process multi-mode and multi-band echo information from a single set of pulse firings is provided. Raw ultrasound signals are digitized and stored in an I/Q data buffer. The stored data are then parallel preprocessed as a function of frequency band or alternative encoding. Parallel preprocessing optionally includes manipulating the data in respect to different imaging modes. Outputs of the parallel preprocessors are coupled to separate area formers used to simultaneously reconstruct various desired echo information to form a multi-mode or multi-band image. The echo formation process is optionally performed in parallel.
