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: Methods and systems for ultrasound imaging and beamforming with a matrix array of transducer elements are provided. Receive signals of each transducer array element are amplified. The amplified receive signal of each transducer array element is digitized. A delay and weight are applied on the amplified and digitized receive signals. The amplified, digitized, delayed, and weighted receive signals are summed across all transducer elements of the matrix array to form a dynamically focused receive beam. An application specific integrated circuit (ASIC) that is integrated with the matrix array of transducer elements performs such steps.
