Can I view multi-frame or 3D DICOM series?

This viewer is optimized for single-frame 2D DICOM slices, X-rays, and individual CT/MRI frames.

Is this tool intended for primary diagnostic use?

No. This viewer is designed for educational, research, and review purposes only. It is not an FDA-approved diagnostic medical device viewer.
