About
LumaDICOM — view your CT, MRI, and X-ray scans on iPhone and iPad.
LumaDICOM opens the DICOM files your hospital, clinic, or imaging lab gave you (CD, USB, archive, or download link) and turns them into a fast, clear viewer right on your iPhone or iPad — no account, no cloud, nothing leaves your device.
Explore any study as 2D slices, as a real interactive 3D volume you can rotate and cut through, or in full MPR with all three planes at once.
WORKS WITH
• CT (computed tomography)
• MRI (magnetic resonance imaging)
• X-ray, CBCT, PET, and other DICOM images
• Folders, ZIP / RAR / 7z archives (incl. password-protected), or a shared cloud link (Google Drive, Dropbox, Yandex Disk)
2D VIEWER
• Scroll through every slice
• Axial, coronal and sagittal planes
• Ruler / distance measurement with a magnifier
• Brightness & contrast (window/level)
3D VOLUME RENDERING
• Smooth, real-time rotation and zoom
• Volume and X-ray looks
• One-tap tissue presets: bone, soft tissue, vessels
• Clipping planes to cut inside the body
• Adjustable lighting and shadows
MPR — MULTI-PLANAR RECONSTRUCTION
• All three planes at once with a linked crosshair
• Oblique reformatting (tilt the planes)
• Slab thickness (MIP / average)
• Ruler on every plane
• Anatomical orientation labels (R/L/A/P/H/F)
MORE
• Panoramic (OPG) reconstruction for dental CT
• Export a 3D model as OBJ / STL for 3D printing
• Organize studies into groups, sort your library
• Share a study with one tap

What's New in LumaDICOM

September 2, 2026
Opens JPEG-LS studies — a compression some scanners and cloud-film services use; those slices used not to load. A clinic's disc image (ISO) is recognized even inside an archive and without an extension. Portal pages that redirect to the archive are followed automatically. Clear guidance for video clips (ultrasound) and 3D models (STL). Thank you for your reports!
