Transport Standards
• SOAP (Simple Object Access Protocol)• XML (W3C)

Security• A symmetric 128 bit fixed-block cipher
algorithm capable of using a 128, 192, or 256 bit encryption key
• An encrypted and integrity protected link to be implemented (e.g., TLS, IPv6, IPv4 with IPsec).

• HL7 is an ANSI-accredited Standards Development Organization (SDO) operating in the healthcare arena.
• HL7 v2.x: Communication layer (Interaction and Message models)
• HL7 v3: Objects layer (Information model – RIM and Document – CDA)
• HL7 FHIR: Fast Health Interoperable Resources
What is Health Level Seven (HL7)?

How to Harmonize different standards – e.g., HL7 and DICOM?HL7 communicates Clinical and Administrative (ADT) data between HIS and RISDICOM communicates between RIS and PACS for images and DICOM modality work list querySo there needs to be a Broker to communicate between HL7 and DICOMIHE Scheduled Workflow (SWF) integrates the ordering, scheduling, imaging acquisition, storage and viewing activities associated with radiology exams.
