1. IHE Radiology Webinar IHE-Japan National Extensions July 25th, 2016

2. Why National Extensions in IHE?
“National extensions … address specific local healthcare needs and promote the implementation of the IHE Technical Frameworks.”
“They may add (though not relax) requirements ...” so
Supporting the international Technical Framework is always step 1
Supporting a NEX doesn’t make you incompatible with the international TF
NEX appear in a TF Volume in each domain (e.g. IHE Radiology TF-4)
Examples:
Require support of character sets and national languages
Provide translation of IHE concepts or data fields from English into other national languages
Changes to institutional information and financial transactions to conform to national health system payment structures and support specific local care practices

3. Focus of IHE-Japan NEX
