What is RIS?
RIS stands for Radiology Information System. RIS is the core system responsible for managing workflow within a radiology department. Tasks include patient scheduling and tracking, examination performance tracking, examination interpretation, billing, and handling of radiology reports including result distribution. RIS must work optimally with the PACS to properly enable information sharing. Over the past several years, with the evolution of radiology to filmless environments, RIS capabilities have increased tremendously in addition to merging of RIS/PACS interdependent functionality.
