Spectroscopy of guinea pig lungs will be studied with the use of hyper-polarized 3He. The goal is to measure the fundamental parameters, T1, T2, T2*, and perhaps D as a function of inflation. Our hypothesis is that one of these parameters will be particularly sensitive to changes in the microstructure of the alveoli.

豚鼠肺的光谱将使用 超极化3He 我们的目标是测量 参数，T1，T2，T2*，可能还有D作为通货膨胀的函数。 我们的假设是，这些参数之一将特别 对肺泡微结构的变化敏感。
