Abstract

The invention relates to a system for noise analysis. The system may acquire a plurality of signals of a subject object and determine a signal representation of the subject object based on the plurality of signals. The system may also determine an updated signal representation of the subject by adding signal interference to the plurality of signals. The system may further determine a noise parameter value indicative of a signal level of the plurality of signals relative to a noise of the plurality of signals based on the signal representation of the subject and the updated signal representation.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 943,198, filed December 3, 2019, and U.S. Patent Application No. 16 / 870,908, filed May 9, 2020, which are hereby incorporated It is incorporated by reference in its entirety. technical field [0003] The present invention relates to a noise reduction technology applied to medical equipment, and more particularly to an active noise reduction technology or active noise cancellation technology (English full name is active noise cancellation, English abbreviation is ANC) to eliminate medical equipment (for example, MRI equipment). Systems and methods for noise at target locations in ). Background technique [0004] Magnetic resonance imaging (MRI) is a widely used medical technique that generates images of regions of interest (ROIs) by utilizing powerful magnetic fields and radio frequency (RF) techniques. A subject (e.g., a scan subject or a body part thereof) can be pl...
