Abstract
Certain exemplary embodiments of the present invention comprise a device comprising a cast computed-tomography collimator descended from a lithographically-derived micro-machined metallic foil stack lamination mold. Certain exemplary embodiments of the present invention comprise a method comprising filling a mold having a stacked plurality of micro-machined metallic foil layers with a first casting material to form a first cast product; demolding the first cast product from the mold; filling the first cast product with a second casting material to form a cast computed-tomography collimator; and demolding the cast computed-tomography collimator from the first cast product. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. This abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
