Description
The Image Viewing Solution (IVS) mobile application (app) allows U.S. Department of Veterans Affairs (VA) clinicians and other medical professionals to search for and view patients’ clinical images. The IVS aggregates images from VA enterprise medical facilities, offering easily accessible diagnostic-grade images, capabilities to work with images (e.g., scrolling, panning, zooming, adjusting window/level) and a tool to collaborate with other VA clinical staff.
The IVS App protects Personally Identifiable Information (PII) and Protected Health Information (PHI) as well as the fidelity of the image, ensuring IVS usage is HIPPA compliant and that images cannot be manipulated.
PLEASE NOTE: Image Viewing Solution is a web app that can be bookmarked on your mobile device. Read the instructions here.
Features:
- Find patient’s by searching specific archives or all of VA’s databases
- View and work with images in the IVS Study Browser
- Collaborate with other health care professionals
- View images from different perspectives (e.g., 2D, MIP/MPR, 3D)
- Work with images in a variety of ways, such as zooming, flipping, highlighting and measuring on an image

Frequently Asked Questions
- Scroll (several lines with an up and down arrows icon) – When selected, click and drag up and down to scroll through the images in a series. This view is available for 2D and MIP/MPR view modes only.

If you are viewing two or more images at one time, you can link your views together so that when you scroll through one image, the other images scroll simultaneously. Or you can unlink your views so that if you scroll through one image, the others remain fixed.
