Abstract: File verification is provided for medical imaging systems, other medical systems or other systems. The verification is performed on an install media prior to installation. For example, data for an upgrade package is transmitted over a computer network. The data is then copied to a compact disc or the RAM of a system to be updated. The copy on the compact disc or the RAM of the system to be updated is verified. Multiple verifications may be performed, such as verifying received data before copying to an install media, verifying on an install media remote from a system to be updated, and verifying on the system to be updated. The verification may be performed separately for each of a plurality of different files in an upgrade package or on an install media. In one embodiment, an MD5 algorithm is used for verification.
