This Small Business Innovation Research Phase I project aims to develop a multi-coil surface NMR imaging for 3-D groundwater imaging and characterization. Surface NMR techniques are generating interest in the groundwater exploration community because of their unique ability to directly detect groundwater, and to distinguish between bound and unbound groundwater. Present surface NMR techniques can produce, at best, an estimate of the 1-dimensional groundwater density profile directly beneath the coil. These 1-D profile estimates are subject to a variety of errors stemming from the use of a single surface coil, and inaccurate 1- D models of the coil fields and water density profiles. The goal of this project is to develop a 3-D surface NMR groundwater imaging system based on coherent multi- coil array processing. The commercial impact of this technology will be an inexpensive, low-energy and non-invasive groundwater exploration method. This technology could have significant positive impacts on both world health and natural resource management.

该小型企业创新研究第一阶段项目旨在开发用于地下水三维成像和表征的多线圈表面核磁共振成像。地表核磁共振技术正引起地下水勘探界的兴趣，因为其独特的直接探测地下水的能力，以及区分结合和非结合地下水的能力。目前的地表核磁共振技术最多只能估算出线圈正下方的一维地下水密度剖面。由于使用单个表面线圈，以及线圈场和水密度曲线的不准确的1-D模型，这些1-D剖面估计受到各种误差的影响。本课题的目标是研制一种基于相干多线圈阵列处理的三维地表核磁共振地下水成像系统。该技术的商业影响将是一种廉价、低能耗和非侵入性的地下水勘探方法。这项技术可以对世界卫生和自然资源管理产生重大的积极影响。
