Mayo Clinic has developed an in-house medical imaging exam tracking system to enable the monitoring of a patient's radiation exposures over time.

The DICOM Index Tracker is being used at Mayo sites in Scottsdale, Ariz., and Rochester, Minn. The application tracks dose and scanner utilization, among other information, for any type of digital imaging. Data is converted into an accessible format and placed in a central repository.

The tracker "learns" about new scanner versions as they are encountered (each version may encode information differently), and builds up a knowledge base to enable a standard set of queries, says Steve Langer, the system's architect.
