Course Objectives
You will be able to:
- Distinguish between the different health care IT domains and identify applicable standards (DICOM/HL7) .
- Identify which interface standard and standard component impacts workflow, presentation of information and image quality.
- Analyze and compare interface specifications.
Skills Taught
After the course you will be able to:
- Specify which standards and services/profiles to be used for successful integration.
- Evaluate vendor proposals for health care IT implementations from a technical integration perspective.
- Interpret the basic DICOM and HL7 message structure and IHE profile definitions.
Course Contents
Lesson 1: Healthcare Standards
After this lesson you will be able to:
- Classify the various interface components into different levels.
- Extrapolate standardization beyond physical, network, and application levels.
- Compare the DICOM, HL7 and IHE definitions.
- Distinguish how some standards use a client server mechanism and how some are trigger event based.
- Analyze the role of DICOM, HL7 and profile definitions such as defined by IHE in the context of interoperability and integration.
Lesson 2: HL7
After this lesson you will be able to:
- Interpret the different segments from a HL7 message and identify their function.
- Analyze a HL7 message using a sample registration and report transaction.
- Recall the most important messages in the context of medical imaging, i.e. orders, admissions and results.
- Recognize the various HL7 2.x versions and detect how backwards compatibility is achieved.
- Discriminate the most important fields in a typical message through its easy to interpret ASCII text encoding.
Lesson 3: DICOM Protocol and Encoding
After this lesson you will be able to:
- Distinguish the difference between the DICOM Protocol components and DICOM data formats.
- Analyze for a connection the two steps in the DICOM protocol, i.e. negotiation and negotiated information transfer .
- Interpret the definition of SOP Class and Instance and how it is used to define device functionality.
- Recognize the different roles (SCU, SCP) for each DICOM service and explain workflow impact.
- Investigate a DICOM dump understanding the VR encoding of attributes.
- Determine how codes from the different vocabularies are used in the context of the DICOM data formats.
Lesson 4: DICOM Services
After this lesson you will be able to:
- Specify which DICOM services apply to what parts of the imaging workflow and map these accordingly on the various activities.
- Recognize the various DICOM services in a vendor interface specification and identify the impact of their presence or non-presence on the workflow.
- Specify which DICOM services are required for serviceability (Verification), basic image and information communication (Store, Query/Retrieve) and image and information management (Modality Worklist, Storage Commitment and Modality Performed Procedure Step).
- Formulate the importance of image quality, and consistency as well as persistency, in the form of DICOM Presentation State and DICOM Greyscale Display Function support .
Lesson 5: IHE
After this lesson you will be able to:
- Apply the various IHE profiles to limit choices in using the standards to increase interoperability.
- Classify the various system components into actors and transactions.
- Analyze workflow diagrams as specified being part of a specific profile definition.
- Distinguish the IHE profiles and categorize them according to the various domains.
- Specify which profiles are critical to support the imaging and reporting workflow.
