Abstract: An ultrasound imaging system integrated on a chip for autonomous scanning includes an on-chip input memory configured to store scan sequence instructions and parameters, an on-chip processor configured to read the scan sequence instructions and parameters in the input memory, and an on-chip beamformer configured to be programmed and timed by the processor according to the scan sequence instructions and parameters. In some examples, the scan sequence instructions and parameters are stored in a nonvolatile input memory programmed at the factory. In other examples, they are received from an external user device. The scan parameters are optimized or minimized to accommodate the limited input memory capacity. In some examples, the scan sequence instructions and parameters include programmable nested loops, and each of the programmable nested loops corresponds to a transmit and/or receive event in a scan sequence.

Abstract: The present disclosure provides an ultrasound imaging system comprising an array of transducer elements, a plurality of receive circuits configured to provide one or more output signals, a plurality of delay circuits configured to output one or more delayed signals, and at least one multi-channel beamformer configured to (i) receive representations of a plurality of microbeamformed signals and (ii) output at least one representation of a beamformed signal. The plurality of microbeamformed signals may represent a combination of delayed signals from the plurality of delay circuits. The plurality of delay circuits may be characterized by a plurality of time delay values. The plurality of time delay values may be controllable or adjustable such that one or more points-of-focus characterizing the microbeamformed signals can move along a line of sight.
