Abstract
Method and apparatus for generating a large-field, high-resolution digital image of an object by sequentially generating multiple optical scenes representative of different portions of the object, and then sequentially directing each optical scene onto an optical detector to generate multiple sub-images of the different portions of the object. Each scene is induced using a separate X-ray sub-beam, each of which is generated by spatially filtering a portion of an incident X-ray field with a spatial filter moving in concert with the scene-directing device. Once generated, the sub-images are combined to form the large-field, high-resolution image.
