Radiology information system
A radiology information system (RIS) is the core system for the electronic management of imaging departments. The major functions of the RIS can include patient scheduling, resource management, examination performance tracking, examination interpretation, results distribution, and procedure billing.  RIS complements HIS (Hospital Information Systems) and PACS (Picture Archiving and Communication System), and is critical to efficient workflow to radiology practices.
Radiology information systems commonly support the following features:
- Patient Registration and scheduling
- Patient List Management
- Interface with modality via Work-list.
- Radiology Department workflow management
- Request and document scanning
- Result(s) Entry
- Reporting and printout
- Result(s) Delivery including faxing and e-mailing of clinical reports
- Patient Tracking
- Interactive Documents
- Technical Files Creation
- Modality and Material management.
In addition a RIS often supports the following:
- Appointment booking
- PACS workflow
- Custom report creation
- HL7 interfaces with a PACS. HL7 also enables communication between HIS and RIS in addition to RIS and PACS.
- Rule engines
- Electronic health record (EHR)
- Hospital information system (HIS)
- Picture archiving and communication system (PACS)
- Medical imaging
- Medical software
