Abstract:
Terahertz imaging has been previously shown to be capable of distinguishing
normal breast tissue from its cancerous form, indicating its applicability to breast conserving
surgery. The heterogeneous composition of breast tissue is among the main challenges to
progressing this potential research towards a practical application. In this paper, two
concentration analysis methods are proposed for analyzing phantoms mimicking breast tissue.
The dielectric properties and the double Debye parameters were used to determine the
phantom composition. The first method is wholly based on the conventional effective
medium theory while the second one combines this theoretical model with empirical
polynomial models. Through assessing the accuracy of these methods, their potential for
application to quantifying breast tissue pathology was confirmed.

The group used "All terahertz time-domain spectroscopy measurements were conducted in reflection mode
using a TeraPulse4000 system (TeraView Ltd, Cambridge, UK). The system produces THz
pulses with a spectral range from 0.06 to 4 THz."
