Study on Design Development of Magnetic Resonance Imaging (MRI) System

Abstract

The Purpose of this Article to introduce Magnetic Resonance Imaging (MRI) System and study the function of major hardware of MRI like Gradient coil to varying Gradient coil field strength (Gradient strength) linearly across the imaging volume for spatially encode the positions of protons. Methods of Gradient Coil design are classified into Coils with Discrete Windings and Coils with Distributed Windings. Magnetic Resonance Imaging (MRI) System requires the use of gradient coils that generate magnetic fields, which vary linearly with position over the imaging volume. Gradient coils for MRI must therefore have high current efficiency, fast switching with low inductance, linearity of gradient over a large volume, power saving, and EMI/EMC harden.
