摘要

磁共振成像(MRI)是一种基于核磁共振(NMR)现象获得图像的广泛应用技术。梯度线圈是负责编码感兴趣体积(VOI)的元件。在进行梯度线圈设计时，考虑了线性度、电感和电阻。本文研究了电磁和热梯度线圈的特性，并提出了两种冷却系统。最后，在双平面永磁系统中对梯度线圈进行了测试，得到了二维幻像。

Feasibility study of a gradient coil for a dedicated and portable single-sided MRI system

Magnetic Resonance Imaging (MRI) is a widely used technique to obtain images in different applications based on the nuclear magnetic renonance (NMR) phenomenon. Gradient coils are the responsible components for encoding the volume of interest (VOI). Linearity, inductance and resistance are taken in account to perform the gradient coil design. In this work, EM and thermal gradient coil properties are studied and two cooling system are presented to cool them. Finally, the gradient coils are tested in a biplanar permanent magnet system and a 2D phantom image is obtained.
