Claim:
1. A method of reconstructing an image, comprising: fixedly placing a predetermined number of energy differentiating detectors around an object along a first path; moving at least one radiation emitting source along a predetermined second path outside the first path while continuously emitting radiation towards the object, the fixedly placed energy differentiating detectors being stationary on the first path with respect to the moving radiation emitting source; detecting spectral data at the energy differentiating detectors; reconstructing an image based upon the spectral data; and providing an outer high-Z material shielding layer and an inner low-Z material shielding layer on at least an outer surface of each of the energy differentiating detectors, the outer surface being closer to the radiation emitting source than an inner surface of the energy differentiating detectors.
