Abstract
A collimator includes a first plate having an aperture therein, the aperture configured to allow passage of a beam of x-rays from a source of a multi-spot source therethrough, and a second plate parallelly positioned with respect to the first plate and configured to receive and attenuate a first portion of the beam of x-rays passing through the aperture in the first plate, the second plate having an aperture therein configured to non-concentrically overlap the aperture in the first plate, to receive a second portion of the beam of x-rays passing through the aperture in the first plate, and to allow passage of the second portion of the beam of x-rays therethrough. A portion of the aperture in the first plate and a portion of the aperture in the second plate form a composite aperture parallel to the beam of x-rays, the composite aperture configured to allow passage of the second portion of the beam of x-rays through the first and second plates.
