This proposal requests support for research that will explore fundamental questions related to Nuclear Magnetic Resonance (NMR) experiments conducted in very-low magnetic fields and opportunities related to a very new imaging modality, called Magnetic Particle Imaging (MPI). NMR is a very-well established experimental technique that uses magnetic fields to probe the nuclei of atoms. It has many applications in science, engineering, and medicine, and forms the basis for Magnetic Resonance Imaging (MRI). MPI is in some respects similar to MRI. It also makes use of magnetic fields; but instead of probing nuclei, it is able to detect and rapidly map out the distribution of very small biocompatible magnetic particles. These particles are so small that they can be injected into the bloodstream as tracers, opening the door to what researchers hope will become powerful method for cardiovascular imaging.

该提案要求支持将探索与在极低磁场中进行的核磁共振（NMR）实验相关的基本问题以及与称为磁粒子成像（MPI）的新成像模式相关的机会的研究。NMR是一种非常成熟的实验技术，它使用磁场来探测原子核。它在科学、工程和医学中有许多应用，并构成了磁共振成像（MRI）的基础。MPI在某些方面类似于MRI。它还利用磁场;但不是探测原子核，而是能够检测并快速绘制出非常小的生物相容性磁性颗粒的分布。这些颗粒非常小，可以作为示踪剂注入血液，为研究人员希望成为心血管成像的强大方法打开了大门。
