Digital Processing and Information Technology in Imaging


Imaging has moved from a film‐based (hardcopy) to a digital‐based (softcopy) process. The acquisition, transmission, and interpretation of medical images can now be performed free of physical means and via electronic data shuttled from scanning devices to display devices. This has proven to be more efficient and effective – ultimately improving patient care.
