Abstract 

This work presents experimental terahertz measurements of excised formalin fixed paraffin embedded (FFPE) human breast cancer tissues. The data are collected using a terahertz pulsed system operating from 0.1 THz to 3THz. The results represent preliminary investigation of terahertz imaging technique for assessing the tumor margins. The direct imaging method will be compared with inverse scattering imaging methods using the experimental data along with histopathological images as references.





-------The THz imaging setup was conducted using the system TPI Imaga 1000 (Teraview Ltd). The TPI system utilizes a time domain THz ----------
