3DICOM Mobile vs Lumen

3DICOM Mobile allows users to securely access, view, and share their medical imaging on the go from their Apple devices. View compatible CT and MRI scans in interactive 2D and 3D, explore anatomy in multiple planes, and access your imaging records wherever you are. With 3DICOM Mobile, you can: • Access your medical imaging securely from your device • View scans in 3D, sagittal, transverse, and coronal planes • Zoom and pan images for closer inspection • Adjust brightness, contrast, and image opacity where supported • Display tissues with varying densities using windowing controls • Securely share imaging with your doctor or healthcare provider • Load scans when connected to the internet We are committed to protecting your data. Medical imaging is transferred using Singular Health’s Medical File Transfer Protocol (MFTP) and stored with secure auditability measures in place. Important: 3DICOM Mobile is not a medical device and is intended for informational and educational use only. It is not intended for primary diagnosis. For support, please contact our team through the 3DICOM website.

Lumen opens the radiology zip your patient brought in. No upload, no cloud, no signup — just pixels, at native resolution, on every Apple device you own. Designed for healthcare professionals reviewing studies they already have authority to access. Lumen is positioned for education, case review, and second-read scenarios. It is NOT a medical device and is not intended for primary clinical diagnosis. WHAT YOU CAN OPEN • DICOM / IHE-PDI zip archives — the format most patient CDs ship as • ISO 9660 disk images directly, no manual mount or repackage needed • Folders of DICOM files • Open via Files.app, share sheet, or in-app picker • No file at hand? Five sample scans come with the app: real, de-identified CT, MRI and X-ray studies PERSISTENT LIBRARY • Every imported archive lives in your device's Lumen folder, visible in the Files app • Every scan shows a preview of its images, its modality and number of series • Re-open with one tap from the home screen; no re-importing • Delete an archive from its menu — along with all the videos exported from it VIEWING • Full native bit-depth display, with pinch zoom, drag pan, and double-tap toggle • Window/level by drag: vertical for brightness, horizontal for contrast — sensitivity scales with the active window so wide CT and narrow brain windows feel equally responsive • One-tap modality presets (CT: soft tissue, bone, lung, brain, abdomen, liver) • Per-instance metadata sheet with manufacturer, matrix, bit depth, transfer syntax, SOP class, and a built-in radiology acronym glossary VOLUMETRIC TOOLS • Automatic detection of stackable volumes from the slice geometry tags, with a 3D / 4D badge in the browser so you can see at a glance which series are reconstructable • Multi-planar reconstruction (MPR): axial, sagittal, and coronal reformats side by side, with crosshair-linked navigation — tap one plane to jump the other two • Slab projection: maximum-intensity (MIP), minimum-intensity (MinIP), or average over 3 to 50 slices — great for vessels, lungs, and noise reduction • True 3D volume rendering: a Metal-powered raycaster with four rendering modes — Surface (solid skin/bone shell with gradient lighting and per-volume tone presets), Anatomy (coloured tissue transfer function), Volume composite (grayscale translucent depth), and MIP • Tissue isolation presets per modality (bone, skin, soft tissue, lung, liver) — hide everything else from the volume with one tap, no per-slice masking • Two-finger pan, drag-rotate, pinch-zoom, auto-rotate cine, and an axis-aligned clipping plane (sagittal / coronal / axial) for cutting away half the volume to see inside • Save the current 3D view as a PNG snapshot at 2× the on-screen resolution, sharable via Photos, AirDrop, Files, or Mail DYNAMIC 4D ACQUISITIONS • Native support for dynamic contrast-enhanced series (e.g. dyn_eTHRIVE liver MR, perfusion MR, dynamic angio): every timepoint becomes its own 3D volume • Timepoint slider in MPR and 3D with cine playback — watch contrast wash through over time • All timepoints prefetched in the background and persisted to an on-device cache, so scrubbing across timepoints stays instant across launches SHARING • Export any series as an H.264 MP4 at 10, 15, or 30 fps • Saved next to its source archive in the Lumen folder of Files.app • Share via the standard share sheet, or copy to iCloud Drive • PNG snapshots of the 3D view share PRIVACY BY DEFAULT • Everything stays on this device • No analytics on file contents, no account, no tracking SDKs • Patient data leaves the device only when YOU choose to share an export • Lumen never connects to the internet: even the sample scans come with the app • A file that won't open? Lumen explains why and, if you want, emails us the technical details — never names, dates or images Lumen is intentionally positioned as an educational and second-read tool. It is not a regulated medical device in any jurisdiction. See the in-app disclaimer for the full statement.
