Abstract
An improved analog beamformer is described that is used to process the data from a high frequency linear array. This unit is a part of a test system, which has the capability to characterize ultrasound transducer arrays up to 128 elements. Improvements include increasing the accuracy of the dynamic focusing capability and an increased bandwidth of the summing circuit.
