An ultrasound beamformer architecture performs the task of signal beamforming using a matrix of analog random access memory cells to capture, store and process instantaneous samples of analog signals from ultrasound array elements and this architecture provides significant reduction in power consumption and the size of the diagnostic ultrasound imaging system such that the hardware build upon this ultrasound beamformer architecture can be placed in one or few application specific integrated chips (ASIC) positioned next to the ultrasound array and the whole diagnostic ultrasound imaging system could fit in the handle of the ultrasonic probe while preserving most of the functionality of a cart-based system. The ultrasound beamformer architecture manipulate analog samples in the memory in the same fashion as digital memory operates that can be described as an analog storedigital read (ASDR) beamformer. The ASDR architecture provides improved signal-to-noise ratio and is scalable.

An ultrasound imaging system includes a processor that is programmed to operate the system in a normal operating state and two or more lesser power states. The processor lowers the operating power state to a lesser power state upon detecting one or more operating conditions such as no tissue been imaged in a predetermined time limit or that the imaging system or transducer has not been moved in a time limit. Upon awakening from a power off state, the processor implements a lesser power state before operating at the normal operating state to avoid undue power use until the transducer is positioned to image tissue.
