Magnetic Resonance Imaging (MRI) is very useful for examining soft tissue in the body and is still rapidly evolving in capability and increasing in use. One of the limitations of MRI is it tends to not provide exact tissue measurements, instead making relative measurements by comparing the signal in different areas. If fast and exact quantitative tissue measures could be developed for MRI, it could further its ability to offer precise information which would be valuable for medical imaging and industrial uses. Our laboratory specializes in the generation of new MRI methods by exploiting the MRI physics underlying each form of image contrast. Our long term goal is the continual development of novel methods that increase the value of MRI and are based on understanding MRI physics and its relationship to human tissue properties. This research proposal will develop new means of performing quantitative MRI, focusing on three unique quantitative techniques. The three areas of interest are emerging areas of MRI application that require further evolution to become practical tools.

磁共振成像（MRI）对于检查身体中的软组织非常有用，并且在能力上仍在快速发展，并且在使用中不断增加。MRI的局限性之一是它往往不能提供精确的组织测量，而是通过比较不同区域的信号来进行相对测量。如果能够为MRI开发快速和精确的定量组织测量，它可以进一步提高其提供精确信息的能力，这对医学成像和工业用途都是有价值的。我们的实验室专注于通过利用每种形式的图像对比度的MRI物理学来产生新的MRI方法。我们的长期目标是不断开发新方法，以提高MRI的价值，并基于对MRI物理学及其与人体组织特性的关系的了解。该研究计划将开发新的定量MRI方法，重点关注三种独特的定量技术。这三个感兴趣的领域是MRI应用的新兴领域，需要进一步发展才能成为实用的工具。
