Claim:
1. A method for imaging a target, with an x-ray scatter apparatus, in the face of overwhelming air scatter, the x-ray scatter apparatus characterized by a detector plane, the method comprising: a. illuminating the target with a beam of x-rays scanned across the target, the beam characterized by a beam axis; b. detecting x-rays scattered by the target, the x-rays characterized by a scatter per unit area, using a detector characterized by a centroid displaced with respect to the beam axis by at least five feet, thereby generating a detector signal, wherein where the scatter per unit area reaching at least one point in the detector plane of the x-ray scatter apparatus from a position on the target is no more than 10% of x-ray scatter reaching the x-ray scatter apparatus due to intervening air scatter; and c. processing the detector signal to generate an image of the target.
