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

Smarter import. • If the folder you pick contains archives rather than images, the app now unpacks them itself instead of reporting that the files could not be opened. An archive that contains archives is handled the same way. • A clinic disc's Windows viewer (.exe) is first tried as a self-extracting archive, since many of them carry the study inside. If it really is just a program, the app now says so and tells you what to ask the clinic for.
