摘要：
A CT collimator includes a first radiation absorbent lamination having a plurality of apertures formed therethrough. Each aperture formed through the first radiation absorbent lamination is aligned with a respective axis formed between a corresponding pixellating element and an x-ray emission source. The collimator includes a second radiation absorbent lamination having a plurality of apertures formed therethrough, each aperture formed through the second radiation absorbent lamination aligned with the respective axis formed between a corresponding pixellating element and the x-ray emission source. A spacer is positioned between the first and second radiation absorbent laminations.
