Detection of oral and breast cancer fresh tissue using continuous wave terahertz reflection imaging

In this paper, Continuous Wave Terahertz system is utilized to image freshly excised oral and breast tissues. The THz images show significant contrast between tumour and adjacent normal/fat tissues in both breast and oral cancer. The obtained images are compared with the histopathology images for the confirmation. Advanced Artificial Intelligence algorithm is developed in which the THz images at each pixel is labelled based on overlapping of THz and pathology images. The results demonstrate the potential of low frequency THz imaging to differentiate benign and malignant tissue in freshly excised samples.
