A Nontechnical Introduction to DICOM: (Horii, 1997 [11])
"The initial goal in developing a standard for the transmission of digital images was to enable users to retrieve images and associated information from digital imaging equipment in a standard format that would be the same across multiple manufacturers. The first result was the American College of Radiology [12] (ACR)-National Electrical Manufacturers Association [13] (NEMA) standard, which specified a point-to-point connection. However, the rapid evolution of computer networking and of picture archiving and communication systems meant that this point-to-point standard would be of limited use. Consequently, a major effort was undertaken to redesign the ACR-NEMA standard by taking into account existing standards for networks and current concepts in the handling of information on such networks. The Digital Imaging and Communications in Medicine (DICOM) standard was the result of this effort. Its popularity has made discussion, if not implementation, of the standard common whenever digital imaging systems are specified or purchased."
