The Dose Index Registry (DIR) allows facilities to compare their CT dose indices to regional and national values. The information collected is masked, transmitted to the ACR, and stored in a database. Facilities receive quarterly feedback reports comparing their results to aggregate results by body part and exam type.
Participating facilities transmit exam data elements using our proprietary TRIAD™ software. Once we receive the data, we supply your facility with the tools to map the study description exam names to a standardized list of imaging terms.
Once your facility is registered, we will activate your unique facility ID number to allow for data transmission. Your facility administrator will receive an email containing a link to the ACR TRIAD software and installation instruction guide.
The guide will direct you to install TRIAD on a standalone PC or server at your facility. You will configure each CT scanner to auto-send the appropriate DICOM SR object and localizer to the TRIAD installation for every CT exam performed on the scanner. TRIAD will mask and transmit data to the registry and route it to your facility ID.
We strongly encourage you to review the FAQ before installing the software.
Exam-name mapping is required to standardize protocol names which differ by facility or scanner. The DIR has implemented lists of standard name procedures with associated RadLex Playbook ID (RPID) and ACR Common IDs.
Two methods are available for mapping your exams:
Option 1: Use our online Exam Name Mapping Tool
Option 2: Work with RadMapps (available at a reduced cost to NRDR participants)
The American Board of Radiology has qualified the DIR for practice quality improvement (PQI) toward fulfilling requirements in its maintenance of certification program.
