How does cinematic rendering improve medical volume visualization?

Cinematic rendering uses physically-based light simulation to produce photorealistic 3D images of CT and MRI scan data. Unlike conventional volume rendering, it reveals soft-tissue boundaries, vascular structures, and subtle density differences through natural lighting and shadowing. This level of visual clarity helps radiologists identify anatomical details that standard viewers may miss, and helps surgeons better understand complex anatomy during pre-operative planning.

Can I view DICOM files with this tool?

The browser demo uses preprocessed reference datasets for instant visualization. A native desktop application with full DICOM import is in active development — it will open DICOM files directly from your PACS or local storage, with multi-planar reconstruction (axial, coronal, sagittal), Window/Level presets, and clinical measurement tools built in. Your data stays on your machine and is never uploaded. Sign up for early access to be notified when it launches.

Which browsers support this 3D medical volume viewer?

The viewer runs in Chrome 113+ and Edge 113+, which support WebGPU. Firefox and Safari are not yet supported due to missing GPU extensions. Simply open the link in Chrome or Edge on any modern desktop — no installation, plugins, or IT approval required. The application loads directly in your browser and is ready to use within seconds.

Is this viewer suitable for clinical radiology?

This is a visualization and exploration tool for reviewing CT and MRI data with cinematic rendering quality. It is not yet FDA-cleared or CE-marked for clinical diagnostics. However, it is valuable for medical education, case presentation, surgical planning review, and research. The upcoming native desktop version will include diagnostic measurement tools (ruler, ellipse ROI, angle) and is being developed with regulatory compliance in mind.

How it works

From scan to image in seconds

Load your data

Open CT or MRI DICOM series — supports standard DICOM formats from any scanner manufacturer.
The browser demo uses preprocessed reference datasets. The native app imports DICOM files directly from PACS or local storage — data is processed locally and progressively organized for fast display.

See results immediately

Visualization begins instantly and progressively refines to full detail. GPU acceleration ensures fluid rotation, zoom, and cropping even with large volumes.
No need to wait for the complete dataset — start exploring anatomy right away with interactive frame rates.

Fine-tune the view

Physically-based cinematic lighting reveals soft-tissue boundaries, vascular structures, and subtle density differences that standard renderers miss.
Customize tissue highlighting to isolate bone, soft tissue, or vasculature with per-intensity opacity, color, and material control. Adjust Window/Level, crop regions of interest, and rotate freely — all in real time.

Built on proven technology
