ROSSLYN, Va.—The
National Electrical Manufacturers Association (NEMA) published NEMA/MITA DD
P1-2019 Understanding the Limited Usefulness of Detector Dose Measurements
in Modern Medical X-ray Imaging Equipment, a medical imaging white paper that
discusses the origins of detector dose, its historical relevance, and the
impact of the transition from film to digital imaging.
This whitepaper provides a
much-needed reevaluation of the detector dose metric and describes both the
benefits and limitations of this metric within a larger historical context.
“Over the past decade we’ve seen important changes in our approach to medical
x-ray imaging, particularly a shift from film and image intensifiers to digital
solid-state x-ray image receptors,” said Andrew Kuhls-Gilcrist, Leader of
Medical Affairs at Canon Medical Systems USA and chair of the MITA
Interventional Fluoroscopy Workgroup. “Newer technologies produce clinically
useful images over a much larger dynamic range, thereby enabling attention to
shift towards patient dose.”
