The Image & Data Archive (IDA) is run by the Laboratory of Neuro Imaging (LONI) at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute. The laboratory first started managing neuroimaging data for multi-centered research studies in the late 1990's, which led to the development of the IDA. Since that time the IDA has become a nexus for many multi-site collaborations. LONI strives to be a global leader in neuroscience data management and informatics solutions that facilitate data preservation, exploration and sharing.

The Image and Data Archive provides tools and resources for de-identifying, integrating, searching, visualizing and sharing a diverse range of neuroscience data and facilitates collaborations between scientists worldwide. Study investigators maintain complete control over data stored in the IDA while benefiting from a robust and reliable infrastructure that protects and preserves research data to maximize data collection investment.
