VA IHE Success StoryVA IHE Success Story
All VA DICOM image acquisition uses IHE Radiology Transactions to interface modalities to PACS: #5 - Modality Worklist Provided - download patient and study #8 - Modality Images Stored - send images to the PACS.
One interface for 250 different models of instruments! Radiology, ophthalmology, dentistry, endoscopy, pathology, and
cardiology.
VA/DoD DICOM Modality requirements documents: www.va.gov\imaging
The VA will not purchase a new modality unless it supports these capabilities.
