Characterizing rat tissue samples using Terahertz Pulsed Imaging

Terahertz pulsed imaging (TPItrade) is a non-ionizing and non-destructive technique. Image contrast has been seen between normal and diseased tissues in ex vivo measurements. Due to its coherent detection, TPI can easily reveal the dielectric properties of samples and recently it has been used for studying a wide range of biological materials. In this study, we try to differentiate between freshly harvested organ samples from laboratory rats using TPI. Consistent differences in the refractive index and absorption coefficient have been seen. Results show that TPI could be an effective tool to quantify these differences.
