IHE Technical FrameworkIHE Technical Framework
The Document for a domain
Public: www.ihe.net/Technical_Framework
Several Volumes (it’s large)
Vol. 1 – defines the Profiles

IHE Integration ProfileIHE Integration Profile
Integration Profile: The Most Important Term Vendors implement them Users buy them / list them in RFPs
Each Profile defines a Problem / Solution E.g. IHE Scheduled Workflow Profile (SWF) “How do I maintain the integrity of patient demographic & order
information and manage workflow in the Radiology Dept?”
The Profile bundles all the necessary integration for the solution

IHE Integration ProfileIHE Integration Profile
In each Profile in the Tech. Framework: the context is described (Use Cases)
(what real-world problem is addressed) the actors are defined
(what systems are involved) the transactions are defined
(what do they have to do when they talk)

IHE TransactionsIHE TransactionsThe guts of IHE - Vol. 2 of the Technical Framework
This is the product implementation guide
Each Transaction: Addresses a specific exchange of data Selects an existing, open standard (e.g. HL7, DICOM, SMTP, …) Documents how to use the standard to implement the transaction Strictly specified to avoid incompatible implementations (retire
options, clarify data model, etc.)
Re-usable, may appear in multiple Profiles
Defines external interface Does not constrain System internal functions
11IHE Canada Workshop 2006IHE Canada Workshop 2006
IHE TransactionsIHE Transactions
E.g. Query Modality Worklist Transaction [RAD-5]
Details Include: Based on DICOM Modality Worklist Management Service Specifies mapping from HL7 Order to Worklist Procedure Step Refines Matching Key and Return Key requirements
Defines exchange of data between actors Order Filler Actor <-> Acquisition Modality Actor
12IHE Canada Workshop 2006IHE Canada Workshop 2006
IHE ActorIHE Actor
A generalized system function, e.g. : Order Placer Order Filler Audit Repository
Implementers choose which Actors included in system
E.g. Order Filler In the RIS? In a Broker Box? In the PACS? Sure, just implement the transactions assigned in the Profile
Systems may group several Actors e.g. LIS = Order Filler + Lab Automation Manager + Result Tracker
Report Creator Patient Identity Source Document Repository

IHE National ExtensionsIHE National Extensions
Technical Framework is Global
National Extensions are Appendices in TF: Documents national clarifications and extensions Mostly translations and minor variations Additional codes for national practices E.g. Use of a Provincial Insurance Number
Radiology TF - Volume 4 Includes France, Germany, U.S., Italy, U.K. Canadian Extension is near completion

IHE TF SupplementsIHE TF Supplements
“New Profile” Documents Follows Structure of Technical Framework Available on www.ihe.net
Published for Public Comment
Published for Trial Implementation
After becoming “Final Text”, folded into Technical Framework during annual update
