3. 2 VA Healthcare Enterprise 157 Medical Centers & 850+ Outpatient Clinics Serves an active patient population of 5 million veterans All sites acquire DICOM images ½ billion images online ½ million images acquired each day

4. 3 VistA & Computerized Patient Record System

5. 4 Multimedia Patient Record Chart Data Textual chart data Computable data Handwritten and non-electronic chart data Multimedia Data Images, graphics, waveforms, audio, etc. Computerized Patient Record and VistA Imaging

6. 5 Wide Variety of Images Integrated with the Online Patient Record Cardiology Bronchoscopy Gastrointestinal Endoscopy Hematology Pathology Surgery Nuclear Medicine Dental Radiology Dermatology Ophthalmology Podiatry Vascular Urology Nursing Electrocardiography Scanned Documents

7. 6 VA 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 www.va.gov\imaging The VA will not purchase a new modality unless it supports these capabilities.
