Abstract
A multilayer collimator for a radiation detector comprises a first layer of a first attenuator material and a second layer of a second attenuator material, each having a coincident opening therethrough. The second attenuator material has an atomic mass smaller than that of the first attenuator material. The second layer continues into an extension departing from the plane of said second layer. There is at least one location in said second layer where a normal to the surface of said second layer passes through a part of said first layer and into said extension, for locking said first layer and second layer into an assembled configuration of the multilayer collimator.
