研究了区域温度分布对二维核磁共振t1成像的影响。局部温度的变化在相应的t1图像中表现为变化。在水和血液样本的情况下，评估了核磁共振t1成像在温度测量中的潜在用途。使用温度已知或以合理精度直接控制的容器，在不同温度下样品至少有2个区域，从而获得图像。如预期的那样，t1在0度范围内与1/T呈线性变化。到40度左右。C代表血液。还讨论了t1成像在热疗应用中的潜在用途。
The effects of regional temperature distribution in 2-dimensional NMR T 1 imaging is studied. Variations in local temperature appear as variations in the corresponding T 1 image. The potential use of NMR T 1 imaging in temperature measurements is evaluated in the case of water and blood samples. Using containers where the temperature could be either known or directly controlled with reasonable accuracy, images are obtained with samples having at least 2 regions at different temperatures. As expected, T 1 is found to vary linearly with 1/T over the range of 0.degree. to about 40.degree. C for blood. The potential use of T 1 imaging in hyperthermia applications is also discussed.
