NEMA XR 28-2013 Supplemental Requirements for User
Information and System Function Related to Dose in CT.
NEMA XR 28 identifies uniform and standardized manufacturer’s information provided to users of a computed tomography (CT) scanner. This information includes perfusion scanning, use of Automatic Exposure Control, organization of dose-related information, and a requirement for listing the reference protocols shipped on a CT system.
This standard is intended to provide instructions to manufacturers so users are provided with uniformed information. It is important that CT scanners have a pre-populated Dose Check Alert value entered by the manufacturer prior to turnover to the customer. This action ensures Dose Check is set at an initial established Alert value.
NEMA XR 28 represents one of many initiatives manufacturers have undertaken to reduce radiation dose exposure through developing standards and implementing equipment features, e.g., SmartDose and Dose Check.
