In this paper, a programmable time-gain-compensation amplifier dedicated to a 2D piezoelectric ultrasound transducer is presented. It uses an open-loop amplifier structure consisting of a voltage-to-current converter and a current-to-voltage converter. The circuit has been design ...
Predictions of nonlinear ultrasound beams of a medical phased array transducer, steered at 0, 22.5 and 45 degrees, and generated by a forward-wave and a full-wave numerical model are presented. The results from both models show a good agreement in the unsteered situation and in a ...
