Abstract
SummaryMedical imaging is the study of human functions and anatomy through pictorial information. During the past 15 years all new medical imaging modalities introduced are digital-based systems. Firstly the concept of digital imaging, the meaning of spatial and density resolutions, and signal-to-noise ratio is reviewed. Based on these definitions, the current technology in image storage and transmission is discussed including the magnetic disk, the parallel transfer disk, the optical disk, Ethernet, the fibre distributed data interface (FDDI), and Ultranet.Among many image manipulation functions, two simple types which are commonly used in clinical applications are discussed, one for visualization enhancement and the other for quantification.
