A major strength of IROC is the ongoing development of an IT infrastructure that fully integrates informatics and quality assurance (QA) services across the six IROC QA Centers to enable the easy transmission of imaging and RT data sets for receipt, assessment, validation, and archiving. 

IROC will develop a common Web portal for all data entry and a common database of imaging and RT QA data. The seamless sharing of and access to the data sets by the NCTN Groups and associated investigators is envisioned to support trial outcomes analyses.
