Application of THz imaging in tumor diagnosis

(A) The refractive index of THz wave at different frequencies of tumor tissue was significantly different from those of normal tissue (Figure 3A). Figure 3A was adapted from Figure 1 in Yamaguchi et al. (2016), used under CC BY 4.0.

(B) The absorption spectra of THz wave at different frequencies of tumor tissue were significantly different from those of normal tissue (Figure 3B). Figure 3B was adapted from Figure 1 in Yamaguchi et al. (2016), used under CC BY 4.0.

(C) The THz imaging pattern is shown in (Figure 3C).
