New in Voxelis: • 3D is now one tap away on iPhone, right beside Reformat • Eye OCT: one Layers button shows the retinal layer lines; hold it for the line source and the legend • When a CT or MR series cannot be shown in 3D, the app now says why • Every view is marked not for diagnosis

New in Voxelis: • Dental cone-beam CT (CBCT) discs now open with their real scale, orientation letters, Reformat and 3D • ZIP archives up to 1 GB, so a whole patient disc can be imported as it is • Voxelis now speaks 47 languages, including Hebrew, Thai, Swedish, Czech, Greek and ten South Asian languages • Optopol (.opt) eye-scanner exports open directly, with the device's layer lines and a µm scale • Every view is marked not for diagnosis

New in Voxelis: • 3D view of CT and MR series: turn and zoom the volume, choose a look (bone, soft tissue, vessels or skin) and a style, clip it open, and share the picture • ETDRS grid: Place grid now starts at a suggested centre, the thinnest point near the middle of a macular scan, and a tap moves it • Share an ETDRS report as a PDF and a CSV, made on your device with no patient name or ID • Eye images: angles and areas when the file records the pixel size, and a scale bar on fundus photos • Every view is marked not for diagnosis

Voxelis for learning and review, now with tools for reading OCT scans: • Thickness cursor: drag across a B-scan to read each retinal layer's thickness at that point, in µm when the file records its spacing • Height caliper with ends that snap to the layer lines • En-face views of the retina (full, inner, outer, below BM) as mean, max or min projections; tap to jump to that B-scan • ETDRS grid: place it on the fovea to see the nine sector means and the macular volume, when the file records its spacing • Topcon .fda files now show the layer lines the device stored • Every new view is marked not for diagnosis

Voxelis for learning and review, now with: • Eye-scanner files open directly: Heidelberg (.vol, .e2e), Topcon (.fds, .fda), Zeiss Cirrus (.img) and Bioptigen (.oct) exports, from Files, Mail or AirDrop. They are converted to DICOM on your device; nothing is uploaded • When the file records it, you see the eye (OD or OS), a scale in millimeters, the fundus photo with the scan positions, and the layer lines stored by the device software, marked not for diagnosis • Fixes and improvements

Voxelis for learning and review, now with: • A new welcome: try the app hands-on with real CT, MR and OCT sample scans before you open your own • 23 languages, 11 of them new; pick one in Settings and the app's screens switch at once • Experimental, on OCT scans: retinal layer lines computed on your device, and retinal thickness (ILM to BM) under the B-scan and as a map on the fundus photo, marked on the image as experimental and not for diagnosis • OCT B-scans that record their pixel size get a scale bar and distances in µm or mm • The eye (OD or OS) is shown when the file's own tags state it • Compare two series side by side, from the same study or another, each with its own slice, window and zoom; link scrolling when both share a frame of reference • "How to get your scans in": a guide for a USB-C drive, a disc copied on a Mac, a patient-portal ZIP, email, AirDrop and iCloud Drive, with an Import button; and "Why won't my file open?" when an import fails • "Open in" Voxelis for patient-portal ZIP files, disc folders and .dic and .ima files from Mail, Files, WeChat and Safari • Studies in iCloud Drive and other cloud folders are downloaded before import, with progress and Cancel • Patient and study names read correctly in every DICOM character set: Latin, Cyrillic, Greek, Arabic, Hebrew, Thai, Chinese, Japanese and Korean • Mouse and trackpad on iPad and Mac: scroll through slices with the wheel or trackpad, Option-drag to adjust window and level • A warning before you share an image that may show a name in the pixels • See how much space each imported study takes, and delete all imported studies at once • Privacy policy, support and feedback in Settings • Design updates for iOS 27: a tab-style picker in the library, a Settings button that stays in the toolbar, and Liquid Glass on the viewer's controls • Fixes: Compare offers every study in your library, a single imported study opens straight in the viewer, and screens hold up at the largest text sizes and with VoiceOver Voxelis is for education and personal review. It is not FDA-cleared and must not be used for diagnosis.

Voxelis for learning and review, now with: • OCT: open OCT studies and scroll through the B-scans. The fundus photo shows where each B-scan was taken, read from the file itself; tap a line to jump to that scan • Cine: play any series with two or more slices as a loop, at the speed you choose • Angle and elliptical area measurement beside distance; an area also shows the mean and range of its pixel values (HU on CT) • Measure at any zoom and rotation, and drag to draw • No more mode picker: one finger scrolls through slices, two fingers adjust window and level, pinch to zoom, double-tap to reset • Imported studies stay in your library across launches, and can be deleted • Import a whole folder, such as a scan copied from a CD or USB drive • Opens more DICOM files: JPEG Lossless, JPEG-LS, HTJ2K and Enhanced CT/MR • Multiplanar reformat now draws coronal and sagittal views head up, and also works on single-file CT and MR series • Every series opens on its middle slice • iPhone shows series thumbnails under the image • iPad and Mac: drag files onto the window to import them; move through slices with a hardware keyboard • New sample studies, each with at least 10 slices: a chest CT, a brain MR and ten OCT volumes. Three OCT samples can show 11 labelled retinal layer lines supplied with the sample data, marked as an educational annotation, not for diagnosis • Available in 12 languages; choose the app's language in Settings • Fixes for JPEG 2000 and the viewer • A "Not for diagnosis" mark now stays on every image, on shared images and on every PDF page

Refreshed the App Store screenshots so they show what the app actually looks like today. No functional changes in this version. If you are updating from 1.5.2 or earlier, version 1.5.3 corrected window and level handling for 12- and 14-bit CT and MR studies, added support for RLE and deflate-compressed DICOM files, and repaired the bundled sample studies so they render correctly.

An image-correctness release. • Sample studies render correctly. The bundled CT was a damaged file that displayed as a white blur. It has been repaired, and every study now opens at a window derived from its own pixels rather than one fixed setting. • Drag to window. With the WW/WL tool active, drag the image — sideways for contrast, up for brightness. • Anatomical orientation markers. A, P, R and L on the image edges, read from the study's own orientation data and rotating with the image. • 12- and 14-bit studies decode correctly. The darkest tissue in these files used to be misread, washing the image out. • Window values no longer carry a thousands separator. • Larger zoom controls, real thumbnails in the series rail, and a technical readout that no longer sits on the anatomy. • Now runs on iOS 17 and later.

v1.4 — Multi-frame DICOMs finally scrub through every frame. NEW • Multi-frame DICOM correctness. ZIP imports of cine US, NM, and enhanced multi-frame CT/MR now play every frame. • Enhanced multi-frame import — studies with PixelData > 256MB up to the 1GB file ceiling now parse. • Partial-compatibility warning capsule for JPEG/J2K series instead of silent blank frames. • Compact iPad thumbnail rail (92pt) with calm 2pt accent selection. • Zoom percentage joins the frame counter in the canvas overlay. • Long DICOM series descriptions truncated cleanly in the caption pill. • WW slider tinted accent; WL slider tinted orange for at-a-glance distinction. • VoiceOver hint on the Privacy nav-bar button. Educational and review use only. Voxelis is not FDA-cleared and must not be used for primary diagnosis.

v1.3 — Hospital portal ZIPs finally work. Plus a calmer viewer. NEW • ZIP archive import. Drop a .zip from Files, AirDrop, or Mail — Voxelis extracts and imports the contents. • Modality-aware WW/WL preset menu. 13 presets from the OsiriX desktop standard: CT brain / chest-lung / chest-mediastinum / abdomen / liver / bone, MR T1 / T2 / FLAIR / DWI, US. • Unknown DICOM modalities (DX, NM, PT) show their actual code instead of silently masquerading as CT. • Calm one-shot per-session educational-use disclaimer on first study open. FIXED • Imported studies survive app restart. Previous version lost file references after relaunch. • Caption strip on the dark canvas readable in dark reading rooms (was dark-on-dark). • iPad zoom / contrast / rotate buttons gained a visible backplate. • Library Currently viewing card no longer causes layout jitter when switching tabs. • Silent crash on multi-file imports of 50+ files (concurrent parses now bounded). • 1GB file ceiling + ZIP safety guards (zip-slip, zip-bomb, TOCTOU). Educational and review use only. Voxelis is not FDA-cleared and must not be used for primary diagnosis.

Share a DICOM frame for case discussion in one tap — patient details hidden by default.

Voxelis 1.1.1 — design polish and accessibility fixes on top of 1.1. • Redesigned onboarding: punchy icon + headline rows replace dense paragraphs. Read it in 2 seconds, not 20. • Library tab "Imported" renamed to "All" so the bundled CT and MR samples are easier to find. New "X more in All" footer surfaces the rest of your library when you're on Resume, Recents, or Favorites. • Fixed: the patient identity caption no longer overlaps the medical image. Reserved 48pt of clear space at the top of the canvas so anatomy is never obscured. • Fixed: removed a duplicate "Currently viewing" card that showed the same study twice on the library home. • More compact Window/Width and Window/Level sliders — reclaims screen height for the diagnostic canvas. Reset is now a tap on the small counterclockwise icon. • "PHI scrubbed" caption polished to "Patient identity hidden" everywhere. • Frame scrubber moved off the bezel for ergonomic thumb clearance. • Tool picker (Navigate / WW-WL / Distance / Pixel Probe) rebuilt for full VoiceOver support. Reminder: Voxelis is for educational and review use only and is not intended for clinical diagnosis.

Voxelis 1.1 — built around the moments you actually use it. • Share-sheet support: AirDrop, Mail, and Files now open .dcm files straight into Voxelis with one tap • Privacy toggle in the viewer: temporarily hide patient name and study date when sharing your screen, AirPlay, or taking screenshots (a convenience for screen sharing, not a compliance feature) • Distance tool in millimetres: a rough on-screen size reference for review and teaching purposes — not intended for diagnosis or lesion measurement • Favorites and Recently Viewed: pin the studies you return to; both survive cold launch • Broader scanner compatibility: many more real-world studies now open cleanly, including lossless-compressed series where the window/level slider is fully responsive • Redesigned app icon, native to iOS 26 with Liquid Glass Reminder: Voxelis is for educational and review use only and is not intended for clinical diagnosis. Thanks for the feedback that shaped this release.
