The National Electrical Manufacturers Association (NEMA) published NEMA XR 26 Access Controls for Computer Tomography: Identification, Interlocks, and Logs.
NEMA XR 26 applies to the particular functioning of a computer tomography (CT) system (as covered by the scope of IEC 60601-2-44). This standard relates to who has access/permission to use the system for clinical or other uses. This includes the ability to assign specific permissions to selected uses that are above those needed for daily routine scanning, such as the authorization to save protocols and add provisions to secure the user interface based on a manual lock. It contains the functionality for use in a facility’s quality assurance program such as capturing operator and patient information, as well as information related to saved changes in protocols.
This standard is not intended to change the existing service or applications access or permissions currently available on CT scanners, nor is it intended to define all access or quality assurance related functionality.
