Abstract:
:A radiographic technique for processing a large number of human crania was developed to aid in the diagnosis of porotic hyperostosis in a large skeletal population. These images are made directly onto photographic paper, thereby reducing costs and increasing the rate of processing. The technique is especially well suited for radiographing human skeletal material and gives excellent diagnostic image quality.
