High-"eld, high-speed magnetic resonance imaging (MRI) can generate high levels of sound within and around the scanner. The process that produces the gradient magnetic "eld is the primary cause of this noise. With the push to greater background magnetic "eld strength and gradient "eld switching spee
## Abstract ## Purpose: To evaluate the effectiveness of the proposed active noise control (ANC) system for the reduction of the acoustic noise emission generated by a 4 T MRI scanner during operation and to assess the feasibility of developing an ANC device that can be deployed in situ. ## Mater
