Radix DICOM Viewer: CT & MRI

Your clinic handed you a CD or USB stick with your scan on it — and nothing on your phone will open it. Radix DICOM opens it in seconds.

Radix DICOM is a fast, native DICOM viewer. Open .dcm files or entire patient-CD folders, scroll through CT and MRI series, play angiography cine loops, and adjust window/level like the pros do — all on your phone.

OPEN ANYTHING DICOM
• Single .dcm files or whole folders — the patient-CD layout your clinic burns just works, including nested subfolders
• Open .dcm files directly from your file manager, email, or drive with "Open with"
• Multi-frame series: cine playback with play/pause, frame stepping, and a scrubber
• CT, MRI, X-ray, angiography (XA), and more

PROFESSIONAL VIEWING TOOLS
• Window/level presets: Soft Tissue, Lung, Bone, Brain, Abdomen
• Drag directly on the image to adjust window/level, or use fine center/width sliders
• Automatic windowing when the file has no preset
• Swipe to scroll through frames, pinch or double-tap to zoom
• Full DICOM metadata panel: patient, study, series, and image tags

BUILT FOR SPEED
Decoding runs in native Rust code with frame-by-frame loading — series open fast, scrubbing stays smooth even on 100+ frame cine runs, and memory stays bounded on large studies.

PRIVATE BY DESIGN
• No account. No sign-up. No cloud.
• Your medical images never leave your device — the app has no server to send them to
• No ads, no trackers. The only thing the app sends is anonymous usage stats (which features get used) — never your images, file names, or any personal or patient data.

FREE
Every feature in this version is free. No trial, no watermark, no locked buttons.

WHO IT'S FOR
• Patients who want to see their own scans from a CD, USB, or downloaded study
• Medical, radiography, and veterinary students studying imaging
• Anyone who needs a quick, clean look at a .dcm file

Recent changes:
When a study can't be opened, Radix now records anonymous technical details about the file format, so unsupported types can be identified and supported sooner.
No patient data, images, or file names are ever collected.
