  • Method and apparatus for spectral adjustment in digital X-ray imaging
    Patent number: 11147529
    Abstract: A method and system for spectral adjustment for a digital X-ray imaging system. The method includes obtaining a set of initial digital X-ray images and then weight factoring the images to generate a set of weight factored digital X-ray images. The weight-factored digital X-ray images are then combined to generate a composite image that is spectrally distinct from the set of initial digital X-ray images.
