单边核磁共振的灵感来自于石油工业，该工业致力于提高测井工具的性能，以测量井下受限流体的性质。这种非传统的核磁共振实现方式，其中杂散磁场和射频场用于恢复放置在磁体外部的任意大物体的信息，推动了手持式核磁共振传感器的发展。这些设备已经将该技术转移到不同的科学学科。目前的工作给出了审查最相关的磁铁和开发的方法，以产生NMR信息的空间定位区域的样品放置在靠近传感器。当系统地进行时，这样的测量导致“单侧深度剖面”或一维图像。本文介绍了最近和最相关的应用，以及未来的前景，这一日益增长的分支的MRI。(C)2012 Elsevier Inc. All rights reserved.
Single-sided NMR was inspired by the oil industry that strived to improve the performance of well-logging tools to measure the properties of fluids confined downhole. This unconventional way of implementing NMR, in which stray magnetic and radio frequency fields are used to recover information of arbitrarily large objects placed outside the magnet, motivated the development of handheld NMR sensors. These devices have moved the technique to different scientific disciplines. The current work gives a review of the most relevant magnets and methodologies developed to generate NMR information from spatially localized regions of samples placed in close proximity to the sensors. When carried out systematically, such measurements lead to 'single-sided depth profiles' or one-dimensional images. This paper presents recent and most relevant applications as well as future perspectives of this growing branch of MRI. (C) 2012 Elsevier Inc. All rights reserved.
