Digital radiography was introduced in the Royal Adelaide Hospital in September 1997 to the Emergency and general areas of the hospital, and extended into the Intensive Care Unit (ICU) in October 1998. The images are viewed on a picture archiving and communication system (PACS) workstation where available, or a personal computer monitor.


(Langlois, Le, Vytialingam & Aziz 1999) This usually results in more efficient patient management and better patient outcomes.
The term "picture archiving and communication systems" (PACS) is used to describe the technologies that are eliminating film. Other terms that may reflect the PACS concept more accurately include "the film-less radiology department" and the "all-digital radiology department." The PACS concept is not new and, in fact, dates back to the 1950s, when Albert Jutras, MD, first conceived the idea of teleradiology . (Bronson 1998) The US government led the development of this technology, and the first film-less radiology departments in the United States were at military hospitals and the Veterans Administration Medical Centre in Baltimore. A decade ago, imaging studies performed by the military in the Middle East during Operation Desert Storm were transmitted digitally and interpreted by radiologists stationed in the United States.
When used for radiology services, PACS must have images in digital format, be able to store them, and provide access for interpretation by radiologists and review by other physicians. (Huda & Szeverenyi 1999) Images often can be directly acquired in a digital format, but sometimes they must be converted to such a format. ...
