    RGB-colored material discrimination for radiography by multi-monochromatic spectroscopy

    We have tried to estimate the power of the material discrimination by performing the radiographs and CT images with using the diffracted monochromatic x rays. Moreover these images were applied to energy subtr...

    Evaluation of energy-subtraction CT images using diffracted monochromatic x rays

    The energy subtraction (ES) method is a technique that eliminates one tissue with the same attenuation coefficient by subtraction between two kinds of images obtained for x rays with different energy. Recently...

    Examination of energy subtraction method by using diffracted monochromatic x rays

    The purpose of this research is to apply monochromatic x rays to the energy subtraction (ES) method. The ES method is a technique that eliminates an image of an arbitrary material by subtracting two images acq...
