Abstract
We investigated the water contents in several organ tissues such as the liver, spleen, kidney, and brain tissue of rats using the terahertz spectroscopic imaging technique. The water contents of the tissues were determined by using a simple equation containing the absorption coefficients of fresh and lyophilized tissues and water. We compared the measured water contents with the difference in mass of tissues before and after lyophilization. All results showed a good match except for the kidney, which has several Bowman's capsules.
摘要
我们使用太赫兹光谱成像技术研究了大鼠肝脏、脾脏、肾脏和脑组织等多种器官组织中的含水量。通过一个包含新鲜组织、冻干组织和水的吸收系数的简单公式来测定组织的含水量。我们将测量得到的含水量与冻干前后组织质量的差值进行了比较。除了具有多个肾小囊的肾脏外，所有结果都显示出良好的匹配度。
