Abstract

This paper describes a new method to determine the lower limit of patient exposure: By placing several imaging plates of a computed radiography system (CR) into the same cassette, several images of the same patient can be obtained at different exposure levels (determined by the x-ray transmission of the various imaging plates. Initial experiments indicate that exposure reduction of between 50 and 75% might be acceptable. CR provides a powerful tool to study the subject of exposure reduction.
