TRIAD: ACR Image and Information Exchange Application

Overview

TRIAD (Transfer of Images and Data) is a workflow based image exchange application that provides secure, efficient, and robust transmission of medical images and related electronic data. Developed and maintained by the American College of Radiology (ACR) with a focus on user-friendliness, TRIAD supports the exchange of electronic images and data for the multi-center clinical trials and other clinical research projects and the ACR’s accreditation programs and National Radiology Data Registry.

In use at hundreds of research sites, imaging facilities and specialized laboratories worldwide, TRIAD securely moves medical images and related data across the Internet to include DICOM images, both structured and unstructured radiology reports, radiation oncology treatment planning data, and electronic health records data. TRIAD meets FDA regulatory requirements under Title 21 CFR Part 11 that governs use electronic records in clinical trials.

A mature product now in its 4th major release, the use of state-of-the-art design methods including adherence to open standards, modular design and industry-wide approaches ensures TRIAD keeps pace with rapid advances in information technology and quickly adapts to new end-user needs.
 

Integration with Third Party Applications

A flexible, service-oriented approach to TRIAD integration with third-party applications has been instrumental in its broad adoption.  Specifically, TRIAD’s application programming interface enables integration with clinical trial management systems (CTMS) and electronic data capture systems (EDC).

Of particular importance, TRIAD is tightly integrated with National Cancer Institute’s (NCI’s) National Clinical Trials Network (NCTN) core systems allowing research personnel at NCTN research sites to submit data and images for the trials that are part of NCTN. Users who will use TRIAD for image management for NCTN trials will utilize their CTEP-IAM user name and password to login. TRIAD also provides DICOM header data to NCTN systems (RAVE) for automatically populating the forms.
 

DICOM Header De-Identification

TRIAD has flexible and rule-based anonymization profile that is created centrally by ACR via a web portal and executed automatically prior to submission from a site during the upload. Anonymization profile can be assigned for a specific trial or a site as needed. A tool for cleaning data that is burned-into images is also available.

TRIAD has a highly configurable process for validating data at the point of transmission.  Rule-based profiles can be created with complex logic that execute automatically upon initiating a transmission.  This validation step can be configured as a hard-stop or simply a warning to the user depending on the business requirement.  User feedback provides the nature of any warnings or violations so that issues can be corrected prior to transmission if desired.
TRIAD Central Services is an application and centralized DICOM, non-DICOM file and metadata storage service located at the ACR’s data center. Central Services also provides centralized transport services to all TRIAD components, DICOM handling, logging, auditing, security and user authentication, and web services to any systems integrated with TRIAD.
