摘要： To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and an output data module may be used to move data for all received channels off-chip as a digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. The on-chip digitization of received signals also enables the on-chip integration of ultrasound processing and/or pre-processing to reduce the burden on off-chip computing. Data compression architectures are disclosed to facilitate the transfer of data off-chip as a digital data stream in accordance with the bandwidth requirements of standard commercially- available output interfaces.

摘要： The present invention provides for generating ultrasound volume images at a higher rate by generating rendered images at the same rate as that of the acquired frames. This is achieved by decoupling acquisition and rendering: 2D frames are acquired continuously and stored in a 3D memory. Once the 3D memory is filled up, old frames are replaced by new frames on the fly. The rendering is performed on the 3D memory at the chosen rate.
