Figure 2. The applications of the multi-energy X-ray detector. (IMAGE)
Caption
a, The reconstructed X-ray spectra obtained from the response signals of the detector, and the simulated X-ray spectra by Monte Carlo, when the driving voltages of the X-ray tube is 45, 55, 65 kVp. b, Schematic diagram of multi-energy X-ray imaging. The X-ray energy from low to high is represented by the color from red to purple. The dark-blue lines represent high-density substance, yellow-green rectangles represent medium-density substance and orange balls represent low-density substance. c, The image of our artificial sample from 2nd electrode. d, The image from 5th electrode. The inset is the optical photo of the sample. e, The subtracted pseudo color image for high density substance CaCO₃ tablet. f, The subtracted image obtained for the low-density paraffin ‘H’ letter.
