Abstract：
:As hospitals convert from conventional film-based imaging to picture archival and communications systems (PACS), methods for managing an enormous library of images must change considerably. While most hospitals are required to retain general, nonmammographic, radiologic images for 7 years beyond the examination date, our pediatric hospital must maintain images until the child's eighteenth birthday, plus the 5-year statute of limitations. Although the physical extent of an electronic archive is tiny compared with a film archive, a long-range strategy is required to ensure that electronic images acquired today can be retrieved and viewed 23 years in the future. Challenges to the long-term stability of the electronic archive include the limited and uncertain shelf life of high-density electronic storage media, the finite maintainability of the electromechanical systems for reading the media, the short product lifetime of software for accessing the images, rapid development of higher density storage products, and the exponential advancement of computer and networking technology that fuels product obsolescence. Since we cannot assure the function of our current archive in two decades, we are committed to a continual process of migration of old electronic image data to newer media and systems. As an early-adopter of PACS technology, Texas Children's Hospital's (TCH) archive management experience is relevant to others. Although not filled to capacity, our first digital archive, based on phase-change write-once-read-many (WORM) technology, was forced into an inactive status by software and hardware changes. Our second set of archives was partially filled with low-density magneto-optical disk (MOD) media, when the drives were upgraded to high density and then filled to capacity. This undesirable situation forced us into shelf management of media. Our third-generation archive is based on a helical tape library with the capacity to contain 7 years of examinations. We will describe the motivation for data migration, limitations in the methods available to perform the migration, and unanticipated benefits of the migration process.
