1. A computer implemented method comprising: capturing a plurality of 2D images of an object using an x-ray source emitting x-rays toward the object and a detector capturing image data of the object, the captured 2D x-ray images being captured over a range of different angles as between the x-ray source and the object; modifying each of the plurality of captured 2D x-ray images to correct artifacts in the images caused by scattering of the x-rays, the step of modifying each of the images including: determining a scatter distribution of the x-rays in an air region near the object; determining a first scatter intensity of the x-rays within a shadow of the object based on the determined scatter distribution; determining a final scatter intensity of the x-rays within the shadow of the object, including modulating the first scatter intensity of the x-rays based on a modulator; and subtracting the determined final scatter intensity of the x-rays from a corresponding captured 2D x-ray image to provide the modified 2D x-ray image.
