The archival process involves de-identifying the header file and securely transmitting the image data from the local site to LONI. The purpose of de-identification is to remove or replace any fields in the header file that have to do with the identity of the subject, such as the Patient Name and ID fields.
A de-identification applet, which integrates the LONI Debabeler technology, allows the user to de-identify files locally, inserting a subject identifier which conforms to de-identification norms, and to validate the changes, prior to transmission. Once the results of the de-identification process have been validated, the files are securely transmitted. Upon arrival, the data is stored in our fault-tolerant storage area network and the database is populated with relevant metadata attributes.
