In the continuing development of terahertz technology to enable the determination of tissue pathologies in real-time during surgical procedures, it is important to distinguish the measured terahertz signal from biomaterials and fluids, such as blood, which may mask the signal from tissues of interest. In this paper, we present the frequency-dependent absorption coefficients, refractive indices and Debye relaxation times of whole blood, red blood cells, plasma and a thrombus.

... Methods Experimental method A stand-alone portable THz system, the TPI Imaga1000 (TeraView Ltd, Cambridge, UK), was used in this work. A full description of the system operation is given elsewhere [19], however it is briefly described here for clarity...
