1. A medical imaging scanner system comprising:
- a medical imaging scanner configured to scan an imaging subject within an imaging area, wherein the medical imaging scanner emits system noise when in operation;
a noise detection device configured to provide a feedback of a predicted system noise based on a selected medical imaging process to be performed; and
an emitter system constructed to emit a signal having properties to reduce perception of the predicted system noise about at least a portion of the imaging area.

Abstract
A system and method for acoustic noise reduction/cancellation is disclosed that includes a medical imaging scanner configured to scan an imaging subject within an imaging area that emits system noise when in operation. An ultrasonic emitter system is included that is constructed to emit an inaudible signal having properties to reduce perception of the system noise about at least a portion of the imaging area.
