Abstract

Owing to the similar absorption between the region of interest and background, an inferior contrast may be shown at the terahertz (THz) image with the reconstruction of unbefitting parameters. In this experiment, due to the small difference of THz pulse between the liver tumor tissue and mirror, the parameter with the sum of the maximum and minimum (SMM) value of the THz pulse was used to reconstruct the THz image. We compared it with the pulse imaging of amplitude (Amp) and maximum (Max) value, indicating that SMM image achieved the best result. K-means and fuzzy c-means clustering results of the two combination parameters (Amp and SMM, Max and SMM) further validate the effect of SMM. The differences of THz pulses from three regions explain the reliable imaging results.
