Abstract:
1. A method of photographing scintillation images originating from within larger and smaller scintillation imaging areas of a scintillation plane, the method comprising the steps of: (a) forming a first optical path for the larger scintillation imaging area by sequentially reflecting a scintillation image originating therefrom with first and second mirrors in respective first and second locations; (b) photographing, with a camera forming a moveable unitary assembly with the second mirror, the scintillation image after reflection by the second mirror in the second location; (c) forming a second optical path for the smaller scintillation imaging area and that is shorter than the first optical path, by locating the second mirror in a third location that intercepts a scintillation image originating at the smaller scintillation imaging area and before that scintillation image reaches the first mirror at the first location; and (d) photographing with the camera the scintillation image reflected by the second mirror in the third location.
