Abstract: Technical advances over the past few years have rapidly increased the possibilities for filmless radiology services provided by picture archiving and communication systems (PACS). PACS is technology to eliminate film from radiology tests in the same way a desktop scanner is technology to eliminate paper in the radiology department. Paperless workflow will allow the radiology department to reduce medical errors, to improve access to critical information, to promote dynamic workload balancing across the department, to support decentralization, and to decrease interruptions. To move from the analog workflow (film, paper) to the digital (filmless, paperless) is main purpose of this workflow. Also it is focused on accelerating productivity for the radiology department and specialty practices, imaging centers, clinics, and hospitals. Paperless workflow will allow manager to reduce administration expenses such as paper, ink, and faxing.
