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

Claim 22:
23. 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 imaging device operates in at least one of:
a low power search mode wherein a reduced number of channels are activated; and
a high power imaging mode wherein a higher number of channels are activated.
