The construction and application of eight different MRI surface coils is described. The coils consist of an anatomically shaped copper wire loop as an antenna and a printed circuit board containing electronic components for tuning and matching. The electronic device for tuning and matching is interchangeable between the various coils. Surface coils for signal detection yield images with high signal-to-noise ratio in comparison to the usual saddle-shaped head or body coils. The sensitivity of a surface coil decreases with increasing distance between the coil and the object of interest and therefore the coils are constructed to fit the anatomical structure under examination as well as possible. The application of dedicated surface coils for superficial structures in the body extends the possibilities of the MRI system. Photographs of the coils positioned on the body and MR images of volunteers and patients are shown.
本文描述了八种不同MRI表面线圈的构建与应用。这些线圈由一个呈解剖学形状的铜线环作为天线以及一块包含用于调谐和匹配的电子元件的印刷电路板组成。用于调谐和匹配的电子装置在各个线圈之间是可互换的。与通常的鞍形头部或身体线圈相比，用于信号检测的表面线圈能产生具有高信噪比的图像。表面线圈的灵敏度会随着线圈与感兴趣对象之间距离的增加而降低，因此这些线圈被设计成尽可能贴合被检查的解剖结构。用于身体浅表结构的专用表面线圈的应用扩展了MRI系统的可能性。文中展示了放置在身体上的线圈照片以及志愿者和患者的MR图像。
