MRI scanners and NMR spectrometers are used by doctors, physicists, chemists and industry scientists and technicians to non-invasively examine a wide range of patients, chemicals, materials and products. These magnetic resonance (MR) instruments are designed and built by electrical engineers. Scanners are usually geometrically closed in order to generate the well controlled magnetic fields necessary for the MR phenomenon to be observed. This limits both the range of samples that can be investigated, and the convenience of MR measurements. My research program develops open MR scanners, using electromagnetic design techniques to generate the same high-quality magnetic fields with open access instrumentation. I focus on low cost instrumentation, which can bring this powerful technology to places where costs were previously prohibitive. Examples are routine industrial quality control measurements, food inspection, and remote medical facilities.

MRI扫描仪和NMR光谱仪被医生、物理学家、化学家和工业科学家和技术人员用于对各种患者、化学品、材料和产品进行非侵入性检查。这些磁共振（MR）仪器由电气工程师设计和制造。扫描器通常在几何上是封闭的，以便产生观察MR现象所需的良好控制的磁场。这限制了可以研究的样品范围和MR测量的便利性。我的研究项目开发开放式MR扫描仪，使用电磁设计技术产生与开放式仪器相同的高质量磁场。我专注于低成本仪器，它可以将这种强大的技术带到以前成本高昂的地方。例如，常规的工业质量控制测量，食品检查和远程医疗设施。
