Data migration challenges PACS vendors and users

A PACS contains different types of data and databases, which have traditionally been stored in different formats. They include image data, demographic data, and DICOM data, as well as functional data such as image enhancement or manipulation performed by the radiologist. Image data may be treated as objects, while patient data may be stored as text. These variables can become major obstacles when migrating data from one archive or one type of storage media to another.
