Abstract
The present disclosure provides a system for active noise cancellation for a subject placed in a scanning bore of a medical imaging apparatus. The system may be directed to perform operations including detecting first noise signals by a first array of noise detection units disposed in the scanning bore, at least part of the first noise signals resulting from an operation of gradient coils of the medical imaging apparatus. The system may also be directed to perform operations including detecting, by a second array of noise detection units, second noise signals near a target position associated with the subject. The system may further be directed to perform operations including determining anti-noise signals based on the first noise signals, the second noise signals and excitation signals used for the operation of the medical imaging apparatus.
