Abstract
A collimator for use in a radiation imaging system and a method for making such collimators, are provided, wherein the collimator is capable of collimating radiation in two orthogonal planes. The collimator in one embodiment includes a block of radiation absorbing material having a plurality of focally aligned channels extending therethrough; in a second embodiment, the collimator includes first and second collimation sections having a respective first plurality of focally aligned plate sets and a respective second plurality of focally aligned plate sets disposed orthogonally to the first plurality of plate sets. The method for making the collimator includes generating a CAD drawing, generating from the CAD drawing one or more stereo-lithographic files, and using the stereo-lithographic files to control an electro-deposition machining machine which creates the channels in the block.
