Investigating the role of water content on the terahertz properties of rat liver cirrhosis

Existing studies terahertz pulsed imaging and spectroscopy to be safe techniques for biomedical applications. Coherent detection in terahertz pulsed imaging enable it to probe a wide range of information of unknown objects in both time and frequency domains. These distinctive features have recently spurred numerous research into human and animal tissues. We previously reported the dielectric properties of normal and diseased rat liver tissues by terahertz pulsed imaging. In this study, further experiments were carried out to understand the observed differences in the optical parameters by looking into the water contents of the normal and cirrhotic specimen.
