Abstract :
An integrated circuit capable of focusing a high-frequency ultrasound annular array is presented. It uses a novel unit-delay architecture to accomplish focusing of the array with a single control voltage. System measurements for a 5-element array indicate excellent pulse fidelity with a dynamic amplitude range of 60 dB at 50 MHz. This is the highest frequency single-chip ultrasound beamformer that has been demonstrated to date.
