Description

一种专用MRI梯度线圈
技术领域
本发明涉及MRI技术领域中的梯度线圈技术领域，具体地说是一种专用MRI梯度线圈。
背景技术
磁共振成像(Magnetic Resonance Imaging，MRI)技术集现代电磁学、原子物理学、量子力学、生物化学以及现代数字信号处理技术于一身，是现代科技高度发展和人类社会高度文明的集中体现之一。相对于其它医学成像方法而言，磁共振成像具有高速、高分辨率、多参数多对比度、无侵入伤害、无辐射等特点和优点。磁共振成像技术成为医学临床最重要的检查手段之一，为人类的健康事业做出了巨大贡献，使其在医学检查中具有重要的临床应用价值。
梯度线圈是MRI系统的核心部件之一，它的主要作用是提供磁共振系统扫描所需的编码磁场。市场上的梯度产品分为通用型和专用型，其中通用型的线圈只有英国Tesla公司和南京磁晨医疗技术有限公司销售成熟的产品，而专用型的产品则需要定制，给专用系统的研发造成了极大的困难。
癌症是当今社会人类健康的头号杀手，在欧美国家，前列腺癌已成为男性健康的头号杀手，而在国内，这种状况也日益凸显，但市场上还没有专用的MRI设备。有人提出了专用的磁共振系统的概念，但该系统需要定制专门的超导磁体、梯度线圈和射频线圈，有较高难度，特别是需要定制一款专用超导磁体，难度和研发成本都会极大提高，阻碍了这款MRI推向市场。
发明内容
针对目前市场对专用MRI系统的需求，本申请提出了一种专用的MRI梯度线圈的设计，该设计基于类马鞍形结构，采用开放的方式，便于应用；特别是这款MRI梯度线圈使用目前通用的超导磁体，降低了研发难度，系统成本也大大降低；其高的梯度切换率满足快速成像需求，同时具有低的外周神经刺激；使用MRI检查生殖系统，大大提高了检查的安全性。
为解决上述技术问题，本申请实施例提供了一种专用MRI梯度线圈，所述的梯度线圈本体整体呈马鞍形结构，包括主线圈和屏蔽线圈，所述的主线圈和屏蔽线圈呈对角设置，中心位置设有FOV空间。
本申请实施例中提供的一个或多个技术方案，至少具有如下技术效果或优点：
本线圈设计基于类马鞍形结构，采用开放的方式，便于应用；特别是这款MRI梯度线圈使用目前通用的超导磁体，降低了研发难度，系统成本也大大降低；其高的梯度切换率满足快速成像需求，同时具有低的外周神经刺激；使用MRI检查生殖系统，大大提高了检查的安全性。
附图说明

图中 ：1、梯度线圈本体，2、主线圈，3、屏蔽线圈，4、FOV空间。
具体实施方式
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
如图1-图2所示，本发明所述的一种专用MRI梯度线圈，该线圈专为男性前列腺、生殖系统或女性腹腔检查用，所述的梯度线圈本体1整体呈马鞍形结构，有开放式设计，满足使用的便捷性，包括主线圈2和屏蔽线圈3，所述的主线圈1和屏蔽线圈3呈对角设置，降低了涡流，能极大地提高系统的性能，成像质量进一步提高，中心位置设有FOV空间4，使用目前通用的超导磁体，降低了研发难度，系统成本也大大降低，FOV空间4，保证了专用系统的成像区域，稳定性高，其高的梯度切换率满足快速成像需求，同时具有低的外周神经刺激；使用MRI检查生殖系统，大大提高了检查的安全性。
以上所述，仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
