Data archiving is an essential component of a PACS system. IMPAX Autopilot manages data in the cache and ensures that it does not run out of disk space. As the cache nears capacity, Autopilot deletes images to make space available for incoming images, usually on a first in, first out basis but ultimately governed by user-defined criteria. In addition to the automated cache management, users with the necessary permission can delete images from the cache.
Details about Autopilot configuration are provided in Autopilot Management. Details about permissions are available in “Defining permissions” (topic number 9451) in the Administering IMPAX component of the IMPAX 6.5.1 Client Knowledge Base: Extended.
Under normal circumstances in which an archive is employed, any data that is deleted from the cache is stored on the archive and no permanent data loss occurs. If, however, an archive is not employed, data deletion results in a permanent loss of the record unless that data has been exported and/or stored elsewhere.
 | CAUTION! Although IMPAX can be used without an archive, we highly recommend an archive be used to prevent data loss. It is the responsibility of any IMPAX customer to recognize and accept these conditions. In addition, granting the permission to delete an image or study from the cache must be carried out with the understanding of the risk it can pose with regard to the permanent loss of patient data. |
