The SmartPACS Viewer (Viewer) is a multi-modality viewer, which allows for the display and manipulation of medical images using an Internet/web browser. The Viewer displays patient studies and other patient data, but does not interpret or provide a diagnosis. The SmartPACS Viewer, when used on tablet devices, is not intended for primary diagnosis.

The application interface is designed to be simple and easy to understand. The application can be used from a desktop with a mouse interface or from a tablet with a touch interface. The application supports the same set of functionalities on both interfaces; however, the interface may differ slightly on a desktop compared to a tablet or a phone. For example, some of the commands on a touch interface are implemented with a multi-touch gesture rather than a button.

By default, the SmartPACS Viewer will open in a new browser tab. This allows you to switch back to the Study List.

You can also configure SmartPACS to open the Viewer in a new browser window or in the same browser tab. This configuration can be found in the System Settings.

Home Button

When the Viewer opens in the same browser tab, an additional Home button appears in the top left corner. Pressing this will take you back to the Study List.


The SmartPACS Viewer is separated into three main sections. The Thumbnail Panel, the Viewport and the Toolbar.

Thumbnail Panel

This is used to select the currently displayed image. It is organized by Study. Each Study can contain multiple Stacks. Stacks are made up of the images in a single Series within the study or the individual frames of a multi-frame Image such as CT or MR images. You can read more about the thumbnail in the Thumbnail Panel section.

Thumbnail Panel


This is the part of the screen where the selected images are displayed.


The Viewport can be customized to display one or many images in many separate viewports withing the entire viewport space. See more here.
