STUDY AND IMPLEMENTATION OF ACTIVE NOISE CONTROL FOR MAGNETIC RESONANCE IMAGING

Abstract

The objective of the Capstone Project is to study and implement the technique called Active Noise Control (ANC).

The project aims to develop an effec- tive ANC system for biomedical appli- cations, namely Magnetic Resonance

Imaging to reduce the noise levels generated during the imaging process. The project involved a combination of

theoretical study, modeling and sim- ulation. The Benchmark ANC algo- rithms (Filtered x-Least Mean square

(FxLMS), Filtered x-Normalized Least

Mean square (FxNLMS) and Fil- tered x-Variable Step-Size Least Mean

square (FxVSSLMS) ) were studied to further compare their effectiveness in terms of the steady-state performance, convergence rate and computational complexities based on the computer simulations.
