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.”
