摘要： An ultrasound reconstruction unit is provided. In one embodiment, a receive aperture control engine for the unit adaptively determines a set of reconstruction signals based on at least a series of selected echo signals and compares the size of a receive aperture with a predetermined number of reconstruction channels at each imaging point. The unit passes the selected echo signals from selected receive channels of one or more transducer elements to a reconstruction processor if the size of the receive aperture is not greater than the number of reconstruction channels. In another embodiment, the control engine compares the size of the receive aperture with a predetermined number of reconstruction channels at each imaging point and preprocess the selected echo signals to produce reconstructions signals that are equal in number to the number of reconstruction channels if the size of the receive aperture is greater than the number of reconstruction channels. The engine then outputs the reconstruction signals for further processing by a reconstruction processor.

摘要： Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.

摘要： An ultrasound imaging method and 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 echo 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.
