Abstract
This work describes an ASIC design for high-frame-rate 3D intracardiac echocardiography probes. The chip is the first to combine element-level high-voltage pulsers and time-gain-compensation analog frontends as well as subarray beamformers and in-probe digitization in a pitch-matched fashion. The integration challenge is met by a shared hybrid beamforming ADC with the highest reported area and power efficiency. The achieved beamformer size of three elements enables acquisition at 1000 volumes/s while, in combination with a custom datalink, still providing sufficient channel-count reduction for catheter integration.
