Elongated radiography cassete with means for exposing reference marks

摘要

A storage phosphor cassette for use in recording radiographic images of elongated objects comprising: first and second storage phosphor plates having first and second length dimensions; a shell having first and second opposite open ends; a first assembly for detachably mounting said first storage phosphor plate in said shell from said first open end; and a second assembly for detachably mounting said second storage phosphor plate in said shell from said second open end, wherein said first and second storage phosphor plates are mounted in said shell such that they form a substantially continuous storage phosphor composite for recording an elongated radiographic image; and an elongated ruler located on the inside or outside of said cassette, said ruler being x-ray translucent/opaque to produce an image of said ruler in said first and second storage phosphor plates. <IMAGE>
