Picture archiving and communications system (PACS) is a filmless and computerized method of communicating and storing medical image data such as computed radiographic, digital radiographic, computed tomographic, ultrasound, fluoroscopic, magnetic resonance and other special X-ray images. A PACS consists of image and data acquisition, storage, display stations integrated with various digital networks. A PACS handling images from various medical imaging modalities is called a full PACS. Small-scale systems that handle images from a single modality (usually connected to a single acquisition device) are sometimes called mini-PACS. A hospital-wide PACS is a PACS which entirely replaces conventional x-ray film by displaying digital images on a network of workstations throughout the hospital. This kind of hospital is called a “Filmless Hospital” (Strickland, 2000). In healthcare environment, the practicing of radiology without X-ray film is called “Filmless Radiology”.
History Of Pacs
The principles of PACS (Huang, 1999) were first discussed at meetings of radiologists in 1982. Various people are credited with the coinage of the term PACS. Cardiovascular radiologist Dr Andre Duerinckx reported in 1983 that he had first used the term in 1981. Dr Samuel Dwyer, though, credits Dr Judith M. Prewitt for introducing the term.
