摘要： An ultrasound imaging system beamforming method comprises reconfiguring the aperture at distinct beamforming instances by i) Increasing the number of channels forming the aperture at a beam forming instance while simultaneously decreasing the sampling rate with an increasing depth of focal point; ii) Increasing the number of array elements that are part of a composite element of a channel forming the aperture at a beam forming instance with an increasing depth of focal point, wherein a composite element is a plurality of individual array elements forming a single channel at a beam forming instance; and/or iii) Defining allowable delay error for each depth of focal point and selecting a base channel for each beamforming instance to form the aperture and selecting additional channels to form the aperture at the beam forming instance which have a delay error relative to the base channel less than the allowable delay error.

摘要： 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 store-digital read (ASDR) beamformer. The ASDR architecture provides improved signal-to-noise ratio and is scalable.
