| 摘 要： | MRI的广泛应用需求不同梯度系统,双梯度系统设计是进行多个独立线圈元素整合的全新概念。这些元素的多样化组合产生不同的梯度水平,高性能梯度系统能成功抑制外周神经刺激。但随着MRI成像术的发展,在MRI的商业应用中,双梯度设计正在逐步被淘汰。本文拟在讨论双梯度的技术细节、应用现状及发展。

| Abstract: | A wide range of MRI applications request different gradient system performances.Dual gradient system design is novel concept comprising multiple and independent coils elements,integrated onto a single former.A variety of configurations of these elements results in a range of gradient performance levels,and successful prohibition of peripheral nerve stimulation while providing high gradient performance.With the development of MRI technology,however,dual gradient system design is being phased out of commercial MRI systems.This article discusses the technical details of dual gradient system,its current status,and its future development. |
