Radiology information system

from Wikipedia, the free encyclopedia

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 .
