摘要
RF线圈(又称探头)是核磁共振波谱仪和磁共振成像仪中的关键部件。根据不同用途,磁共振射频线圈可以分为许多种。研制了一种用于试管样品的高灵敏度微型射频线圈,并在台式磁共振成像仪上进行了相关射频线圈的性能测试,证实了设计的理论和方法。
A RF coil （or probe） is one of the key components in NMR spectrometers and MRI systems, and designing a quality RF coil is a cheaper way to improves the signal-to-noise ratio （SNR） of systems and image quality. According to different applications there are a variety of RF coils. This article describes high-sensitive micro RF coils used in NMR spectrometers specially for test-tube samples. Their performance has been verified on the desktop MRI systems.
