What's New in DICOM Viewer
1.2
October 12, 2026
A picture of a scan is an exam now. Import a PNG, JPEG or HEIC — a photo of a film on a lightbox, a screenshot a doctor sent you — and it opens in the viewer like any DICOM file, with the same window and level, zoom and measurements. Every way in is on the Exams screen: files, photos, a link, or the steps for bringing one over from a Mac or PC. No menu to find first. Given a licence or an access code? Settings → Redeem code takes it, and so does the link it came in. Redeem it once and your other iPhone or iPad picks it up.
