Patent ID: 11971477
Assignee: EXO IMAGING, INC.
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. An imaging device comprising:
an array of transducers, wherein each transducer:
comprises an array of piezoelectric elements;
is fabricated on a semiconductor wafer substrate; and
is connected to sensing, drive, and control circuitry in close proximity to the piezoelectric elements to:
transmit pressure waves towards an object to be imaged; and
receive reflections of the pressure waves off the object to be imaged;

a transmit channel per one or more piezoelectric elements to generate the pressure waves; and
a receive channel per one or more piezoelectric elements to process the reflections of the pressure waves,
wherein the device is configured to selectively alter an operating number of the transmit or receive channels in response to feedback of operating parameters of the device for improving thermodynamic or power efficiencies of the device while preserving image quality.
