Health care professionals use the PACS, or Picture Archiving and Communication System, to upload and store digital images such as pictures from a radiology department. As a remote PACS administrator, you implement the system for your employer, integrate different sources, and monitor the system. Your duties and responsibilities can also include training staff to upload images. A PACS support specialist troubleshoots when problems arise, while analysts assess system performance and help develop or install apps to improve efficiency and reliability.
