In order to obtain a high-contrast image of the "area that user wants to see" using X-ray image sensor with energy discrimination capability, we investigated a method of dividing the X-ray transmission image into data for each energy band and combining them by adding coefficients.
The X-ray images were acquired with a photon counting detector, and the images were obtained in 10 keV increments from 10 keV to 100 keV. Single energy band images for low to high energy bands were considered, and image quality improvement by combining multiple energy band images was discussed.
