Abstract
In some examples, a method to reduce heel effect distortion in dual energy x-ray images includes receiving flood field images generated by x-rays at different energy levels and generating one or more normalize images based on the flood field images. The method may also include applying the one or more normalize images to one or more x-ray images and combining the x-ray images to generate a dual energy x-ray image with reduced heel effect distortion.
