Leask, J W

A collimator for radiation receiving and imaging devices and a method for making such collimators are described. The fabrication procedure includes the steps of casting a plurality of modular elements each having a base from one side of which extends a first plurality of spaced columns and from the opposite side of which extends a second plurality of columns of shorter height than the first directly opposite the spaces between the first plurality of columns, inserting the first plurality of columns of one module into the spaces between the second plurality of columns of the succeeding module in a modified mortistenon relationship successively and affixing them in that position, placing the assembled grid into a frame, and filling the spaces between the grid and the frame with radiation-opaque material, thereby forming an integral functional collimating unit. 14 claims, 5 figures.
