Radiology information system
Radiology information systems (RIS for short) are EDP systems for the documentation and management of medical and administrative data in radiology as well as for process control (e.g. scheduling, resource management).
Functions
Functions of RIS are essentially the
- Administration of patient master data
- Scheduling radiological examinations
- Provision of a DICOM interface to the imaging digital examination devices (the modalities , e.g. CT , magnetic resonance tomography ) via which the patient data can be transmitted (= DICOM worklist).
- Control of the image call in the PACS ; The examination to be assessed is selected in the RIS, and the image data is loaded in parallel to the PACS via the interface.
- Documentation of medical data according to the requirements of the German X-ray Ordinance via DICOM MPPS.
- Documentation of billing-relevant services (e.g. GOÄ , EBM , DRG )
- Creation of radiological findings (today often using speech recognition )
In terms of their functionality, RIS are closely related to hospital information systems (HIS), but are tailored or expanded for the special needs of a radiological department. In many cases there is also an interface between HIS and RIS. Requests from the HIS can be transmitted to the RIS, which in turn transmits findings and / or performance data. HL7 has established itself as the standard for the transmission of this data .
