Anthropomorphic chest phantom imaging the potential for dose creep in computed radiography (2013)
Journal Article
creep in computed radiography. Radiography, 19(3), 207-211. https://doi.org/10.1016/j.radi.2013.04.002

For film-based radiography the operator had to be exact in the selection of acquisition parameters or the
image could easily become under- or over-exposed. By contrast, digital technology allows for a much
greater tolerance of acquisition factor se... Read More about Anthropomorphic chest phantom imaging the potential for dose creep in computed radiography.
