摘要
梯度是核磁系统的重要组成部分,它是影响磁共振成像的重要因素之一,因此,核磁共振在安装前后对梯度均有较高的要求。首先阐述了梯度的原理及作用,随后探讨了核磁共振在安装前后如何合理利用梯度获得最佳的图像质量。
Gradient System is one of the most important parts of Magnetic Resonance Image System, It is a key factor in the image quality. Therefore, during the whole installation process, advanced gradient system is strictly needed. Firstly, this article gives a clear explanation about the theory and function of the gradient system. Then, it discusses how to make rational use of gradient system to acquire the best image quality.
