Lung and Brain window presets in 2D, MPR and 3D — with the window values (W/L) shown above the buttons, workstation-style. Labels and controls stay readable on bright images. When Yandex Disk refuses a download, the app explains why and offers to open the page in the built-in browser. Files without an extension are recognized by their content. Thank you for your letters and reports!

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!

The app now warns you up front when there isn't enough free space to unpack an archive — and tells you how much to free up. Clear guidance for web-portal exports (HTML/XML). Thanks for your error reports!

Minor improvements and fixes.

Clinic portal links now work. If a link opens a page that wants a login or an access code, open it right inside the app: sign in, tap the download button, and the images arrive on their own. And when the page holds a direct link to the archive, the app finds it for you. Clearer messages when the files you picked aren't DICOM: the app names what they actually are — a PDF report or ordinary images — and what to ask the clinic for. Fixed: the density histogram was missing from fine tune on studies with saved settings.

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.

LumaDICOM now runs on iPad — the same interface with a much larger image area, including landscape. Also, DICOM files without the standard file header (seen in older PACS exports) now open.

Downloading by link is now more resilient and noticeably faster: if the connection drops, the transfer automatically resumes where it left off instead of starting over. Download progress is shown more accurately.

• Measurement tools in 2D and MPR: ruler, angle, ellipse ROI (area, mean density, approximate lesion volume) and a live density probe. • Full study details: patient, acquisition parameters, equipment and dose — straight from the DICOM header. • In-app feedback form. • Fixed lighting on cut planes and erased areas in 3D. • New app icon.

• Overlay mode: add a second slice stack to the 3D scene and compare two models — each keeps its own tissue preset, brightness, clipping and eraser settings • Align by points: place 3–6 paired landmarks on both models and the app computes the alignment automatically, with the residual shown in mm • Save settings: enable in the ⋯ menu — everything you tune in 3D, 2D and MPR (including the overlay and eraser) is restored the next time you open the study • Bug fixes and stability improvements

• PRO fine-tuning: a transfer-function curve editor — set tissue colour, opacity and brightness by hand. • MIP mode in 3D — maximum-intensity projection, great for contrast-filled vessels. • Fixed-light mode keeps the light source still while you rotate the model. • MPR: a discreet crosshair that doesn't cover the image. • Clear message when opening scanner-viewer discs (GALILEOS, etc.). • Fine-tuning and stability improvements.

• Added a Simplified Chinese interface. • New 3D eraser — wipe away parts of the volume with your finger to reveal hidden structures. • Even broader DICOM compatibility — more hospital and PACS exports open directly. • Stability and refinements.

• Compressed DICOM support — JPEG 2000, JPEG Lossless, RLE, and JPEG Baseline. Studies exported from most PACS now open directly. • Import a single DICOM file, or pick a whole folder — clearer Add menu. • Open studies shared as HTTP links. • Stability fixes and refinements.

New MPR mode — view all three planes (axial, sagittal, coronal) at once with a linked crosshair. Oblique reformatting, slab thickness, a ruler on every plane, anatomical orientation labels (R/L/A/P/H/F) and zoom sync. Stability and performance improvements.

• Import password-protected ZIP archives • Correct slice (MPR) reconstruction for studies acquired in any plane • Haptic feedback on button taps (can be turned off in Settings) • Smoother slice scrolling and brightness adjustment • Fully localized interface and messages (English / Russian) • Improved catalogue thumbnails and overall stability

• Groups (folders) in your study list — sort exams into your own folders, collapse them, reorder. • Sorting — by date added, examination date, type (CT/MRI/…) and body region. • Export 3D models as OBJ and STL — for 3D printing and viewing in other apps. • Body-region names are now localized (EN/RU). • 3D viewer: front view by default, pause-on-idle to save battery, and a clear message when there are too few slices to build a volume. • Cleaner, more informative study cards. • Minor UI and stability improvements.

• Fixed importing archives that contain non-Latin (e.g. Cyrillic) file names inside — discs and ZIP files from some clinics no longer fail with a "corrupted archive" error. • Added a "Report a problem" button: if a study won't open, you can send us a quick technical report (no images or personal data).

• Adaptive resolution in 3D: smooth rotation even on large CT scans — resolution drops only while you interact and snaps back to full detail when the model is still. • Quick render settings right in the 3D viewer (shadows, lighting, FPS target) — applied per study. • Volume quality now defaults to Maximum for crisper detail. • Interface and stability improvements.

New X-Ray rendering mode in the 3D viewer — switch between Volume and X-Ray to see dense bones with dental work and metal hardware highlighted, in a clinical CT-projection style. Series variants now show their full DICOM SeriesDescription (e.g. "Head 0.6 H80s · 432") so you can tell reconstructions apart at a glance. Cleaner 3D rendering: stochastic jitter removes the concentric "iso-density" banding artifacts that occasionally appeared on smooth bone surfaces. Portrait orientation is now locked — no more broken layout after an accidental device rotation.

What's New in 1.2.1 • RAR and 7z archive support added (in addition to ZIP), for both file import and cloud links (Google Drive, Dropbox, Yandex Disk). • 3D clipping planes: up to three at once, new compact tabbed UI, panel no longer obscures the volume. • 3D viewer: "1×" zoom-reset button moved to the bottom-left corner. • 2D viewer: zoom-out down to 50%; one finger now only adjusts brightness, two fingers pan the image. • OPTG: drag the panorama with one finger to shift the underlying arch — a corner thumbnail with the curve appears while pressed. • Fixed a crash at maximum zoom in the OPTG arch-drawing mode. • Various UI and stability improvements.

• Panoramic (OPTG) view — reconstruct a flat panoramic image of the dental arch from a CT scan, with adjustable slab thickness and a histogram window. • Sagittal and coronal slices (MPR) — in 2D mode you can now view your scan from the side and front, not just from above. • Density fine-tune — a histogram with two handles trims "extra tissue" out of the 3D model. • Clipping planes — slice off part of the 3D model along X/Y/Z to look inside. • Share an examination, or save a panorama image to Photos, via the system share sheet. • 3D quality switch in Settings for crisper side reconstructions. • Ruler and measurements in the side planes, with a magnifier for precise placement. • Fixes: Yandex.Disk import links and exam renaming.
