Te Role of Standards in Reducing Variability

Key Interoperability Standard Driving PACS Data Exchange

Several mature ande emerging standards underpin modern PACS equibility. The most prominent are DICOM, HL7, andFHIR. understanding their ir respective role - and how they complement each exair - is critical for any healthcare organization planning an imaginag data exchange strategy.
