1. RSNA 2003 The IHE Technical Approach Identify the transactions required to integrate information flow between information systems For each transaction, select a single standard for use in implementing the transaction Specify in detail the use of the standard in implementing the transaction

2. RSNA 2003 What is IHE? IHE is a specification of transactions between systems. IHE describes only integration features. IHE is not a product itself, but… IHE is very useful in purchasing products that integrate into workflow

3. RSNA 2003 Integration Profiles - Transactions packaged in solutions- Coherent functional sets of transactions related to workflow 46 Rad. + 13 IT transactions grouped into 12 + 5 Integration Profiles Integration Profiles are the only practical way to communicate integration requirements precisely.
