Abstract: An ultrasonic imaging system has an ultrasonic probe which improves poor harmonic performance of existing transmit circuits through the use of a linear high-voltage transmit amplifier on each sub-channel to amplify low-voltage arbitrary shape transmit waveforms generated by the ultrasonic system. The linear high-voltage amplifier of the ultrasonic probe amplifies low-voltage arbitrary shape transmit waveforms beamformed by a micro-beamformer of the ultrasonic system.

Abstract: An ultrasonic piezoelectric transducer device includes a transducer array consisting of an array of vibrating elements, and a base to which the array of vibrating elements in the transducer array are attached. The base include integrated electrical interconnects for carrying driving signals and sensed signals between the vibrating elements and an external control circuit. The base can be an ASIC wafer that includes integrated circuitry for controlling the driving and processing the sensed signals. The interconnects and control circuits in the base fit substantially within an area below the array of multiple vibrating elements.
