Measuring and annotating scans in 3DICOM
Overview
This guide walks you through adding measurements and annotations to your medical scans, and shows how to explore data using 3D and multi-panel layouts in 3DICOM.
Step-by-step instructions
Add measurements to your scan
Step 1. Open the Measurement menu.

Step 2. Select a measurement tool, such as Bidirectional.

Step 3. Click and drag across the area you wish to measure and click again to complete the measurement.

Explore scan layouts and display options
Step 1. Open the Layout menu and switch between single view, multiple panels, or 3D views as needed.

Step 2. Use your mouse to pan and drag within each panel.

Step 3. Select the Zoom tool to focus on image details.

Step 4. Use Windowing to adjust contrast levels.

Step 5. Change each panel’s orientation (axial, sagittal, or coronal) from the control at the top left corner.

View and interact with the scan in 3D
Step 1. In the Layout menu, select the full 3D only render mode.

Step 2. Rotate, zoom, and change the viewing angle directly on the 3D render.

Step 3. Select 3D Slice to turn the stack of images into an interactive 3D model you can manipulate within the workspace.
