DIGITAL IMAGE STORAGE [PDF]

open access: yesVeterinary Radiology & Ultrasound, 2008
Digital image archival requires less physical storage space, allows for rapid storage and retrieval and avoids loss in image quality over time or with image duplication compared with film storage. Because medical imaging data are critically important and, by law, must be stored in a safe, accessible manner, it is imperative not to have one computer ...
