MPR volume rendering

Build a 3D volume from a series and inspect it with multiplanar reformatting.

Problem

You have a multi-slice CT or MR series and need to view it as a 3D volume with interactive Multi-Planar Reconstruction (MPR) — simultaneous axial, sagittal, and coronal views. Unlike single-slice viewing, MPR renders cross-sectional reformats from the volume in real-time, allowing you to navigate through the anatomy in any orthogonal plane.

Steps

1. Load a multi-slice series (⌘O) — e.g. 8 DICOM slices sharing a Series Instance UID so Cornerstone groups them into one volume.

2. Toggle MPR mode — click the 3D/MPR toggle button in the top bar. Three viewports appear displaying Axial, Sagittal, and Coronal reformats.

3. Wait for volume loading — all three viewports must reach data-volume-ready="true" before interacting. This attribute is set after volume loading and rendering complete.

4. Export an MPR slice — click Export → Export MPR Slice… to save the current slice as PNG (or PNG + DICOM Secondary Capture).

5. The exported slice is captured at native volume resolution with W/L baked in.

Expected Result

• Three MPR viewports render simultaneously (Axial, Sagittal, Coronal).
• Viewports reach data-volume-ready="true" after volume load completes.
• Export produces a correctly oriented PNG with W/L applied.
• The audit log records the orientation and filename of each export.
