A computed tomography (CT) scanning apparatus that includes a set of X-ray sources and a set of flat panel detectors with a set of source collimators and a set of detector collimators therebetween. The design of the openings of the set of detector collimators is such that the images received by the set of flat panel detectors may be combined, or stitched together to generate a single X-ray image.

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.
