DICOM and HL7 have their own, specific application domains. DICOM is mainly for all imaging related applications while HL7 is more for administrative and management purposes. There are also key differences with regard to maturity, sophistication, reliability, and standards conformance.

This technology overview description shows how HIPAA security and privacy can be accomplished by implementing the DICOM digital signatures.

This power point presentation describes the HL7 current standard, including some of the Trigger Events, ADT and ORM messages, CCOW for exchanging context information, and CDA or Clinical Document Architecture as well as EHR or Electronic Health Records. Differences between both DICOM and HL7 are shown and the DICOM protocol in the workflow context. New developments in DICOM are listed.

Image and Information Management (IIM) are addressed by DICOM, HL7 and IHE. Challenges for IIM are large, especially with regard to increase in data volume, new applications and the integration with new modalities. These are addressed in DICOM using DICOM Storage Commitment (STC), Modality Performed Procedure Step (MPPS), new SOP Class definitions, many tools for integration such as Key Images.  HL7 addresses these with new, persistent object definitions, such as CDA and IHE addresses them by specifying many profiles.

This 20 page detailed technical document consists of a detailed DICOM requirements specification to be used by anyone who is considering purchasing a fully DICOM compliant Ultrasound device.
