A series of radiographs of a tissue-equivalent phantom was taken in order to arrive at satisfactory radiographic techniques for the use of rare earth screens with the Panorex II. The radiation reduction needed for use of the rare earth screens was made with various filters. There was a 40% to 60% reduction in patient exposure for all of the rare earth exposures. Raters agreed that all films that were ranked were diagnostically acceptable, although differences were noted.
