2.材料和方法，加上爆炸性增长的ct数字计算机，在过去几年中发挥着重要作用的医学成像。磁共振成像作为一种断层摄影技术已经发展到产生人体内部的图像。脂肪和水是人体的主要组成部分，它们含有许多氢原子。核磁共振成像从氢原子核的核磁共振信号。因此，核磁共振成像的发展提高了我们诊断和监测疾病的能力。由于核磁共振对水和有机化合物的质子磁矩特别敏感，因此埃德尔斯坦和舒尔森（1991）应用核磁共振成像技术来观察盐水冰中的排水通道。Manfres et.艾.（2000年）使用核磁共振技术观察石油扩散到海冰中的过程。虽然已经有几项关于海冰核磁共振成像的研究，但很少有人尝试使用核磁共振来可视化积雪。在这项研究中，开发了一种具有小型温控室的NMR成像系统，然后用于可视化积雪样品。
2. MATERIALS AND METHODS which coupled with the explosive growth ct digital computers, is playing an important role in medical imaging over the last several years. Magnetic resonance imaging has advanced as a tomographic technique to produce images ct the inside of the human body. Fat and water, which primarily make up the human body, have many hydrogen atoms. MRI images an NMR signal from the hydrogen nuclei. Therefore development of NMR imaging has enhanced our ability to diagnose and monitor diseases. Because NMR is particularly sensitive to the proton magnetic moment of water and organic compounds, Edelstein and Schulson (1991) applied NMR imaging to visualize drainage channels within salt-water ice. Manfres et. aI. (2000) used NMR to visualize oil diffusion into sea ice. Although there have been several studies on NMR imaging of sea ice, there have been few attempts to use NMR to visualize snowpack. In this study, an NMR imaging system with a small temperature-controlled chamber was developed, and then used to visualize snowpack samples.
