Recent advancement in Magnetic Resonance Imaging (MRI) techniques for medical diagnosis and biomedical research dramatically reduces scanning time and improves clinical throughput uses powerful gradient magnetic fields with very rapid pulses. However, the rapidly pulsed gradient magnetic field required for fast imaging causes significant vibrations of the gradient coils and surrounding structures resulting in unacceptably high levels of acoustic noise emission. The extreme high level noise can be both annoying and harmful to patients and healthcare workers especially under long term exposure. Previous passive methods have not resulted in a satisfactory level even when ear protections are used. In this study, an active noise control scheme is proposed and studied for a pre-recorded noise from a 4-Tesla MRI scanner. The recorded MRI noise is played back through a high fidelity stereo system in a sound quality studio and controlled using a headset equipped with an active controller. Numerous parameters of the controller is tested and tuned to achieve the best possible performance. The results showed almost 20dB reduction at the principal harmonic and 12 dB overall reduction is achieved.
