Abstract: Method and apparatus for alignment of a collimator in a scintillation camera system. First coarse alignment apparatus includes an alignment plunger coordinated with a first mating member. A recess coordinated with a second mating member is positioned and configured to loosely receive the alignment plunger for coarse alignment. Coarse alignment of the first apparatus establishes a vertical axis for horizontal angular rotation about which angular displacement of the members effects coarse alignment with second, coarse alignment apparatus spaced from the first apparatus. The plunger assemblies are preferably spring loaded so that an audible click is generated when the plunger impacts the bottom of the recess to indicate coarse alignment. The coarse alignment apparatus guides the two members into fine alignment whereupon tight fitting fine alignment apparatus coordinated with the two members is mated.
