Abstract:
1. A method for fabricating an x-ray collimator, comprising: identifying 3-dimensional structures and positions of the 3-dimensional structures in a collimator design; selecting a number of collimator layers; determining 2-dimensional shapes corresponding to the respective identified 3-dimensional structures for each layer; determining, in each collimator layer, positions of the 2-dimensional shapes corresponding to the respective identified 3-dimensional structures for each layer; forming apertures in at least one laminated layer to produce the selected number of collimator layers, each having apertures according to its respective determined 2-dimensional shapes at the respective determined positions; stacking the collimator layers in a position of alignment to form the identified 3-dimensional structures; attaching the stacked and aligned collimator layers to form a composite collimator structure with the identified 3-dimensional structures therein; and honing the 3-dimensional structures within the composite collimator structure.
