Prism (viewer)
Prism — imaging viewer
What Prism is, how to open it, and a guide to every tool available for clinical review.
Prism is Xenrad's built-in diagnostic viewer. When you open a study, Prism loads the DICOM images directly in your browser—no separate application to install or log into separately.
What you can do in Prism
- Read studies in full resolution with window/level presets for common scan types (CT brain, CT chest, soft tissue, etc.)
- Compare multiple series or time points side by side in flexible viewport layouts
- Measure distances, angles, and regions of interest, with annotations saved per session
- Navigate stacks and play cine at adjustable frame rates
- Segment (when enabled for your site) and review segmentation groups
- Switch series quickly from thumbnail strips without leaving the viewer
How to open Prism
From the study detail page, click Open in Prism (or Viewer, depending on your deployment). Prism opens with the study already loaded—you shouldn't need to enter a study UID by hand.
Prism uses your current web app session. If your session expires, image requests will fail. Go back to the app, sign in again, and re-open the study.
