Open CT & X-Ray Scan Files
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Got a CD or a folder of scan files from the hospital and no way to open
them? This app opens them in seconds, right on your iPhone, iPad or Mac.
It reads CT, MRI, X-ray, ultrasound, PET and more. Everything stays on
your device. No account. Nothing is uploaded.
TRY IT BEFORE YOU IMPORT ANYTHING
Tap Import, then Sample exams, and the app downloads a real chest CT,
chest X-ray, pelvis MRI or chest ultrasound so you can test it right
away.

READ THE IMAGES
- Set brightness and contrast by dragging, with CT presets for brain,
lung, bone, soft tissue and vessels
- Scroll a stack, zoom, pan, rotate, flip, invert and play as a movie
- Put two series side by side, linked by position, so different slice
thicknesses stay lined up

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
An introduction the first time you open the app, so you know what it reads and where your exams stay before you hand it one.
DICOM Viewer Pro: open as many exams as you like, reformat a CT or MR series in three planes, render it in 3D and export an STL, search and exchange exams with PACS servers, and export DICOM files with the names removed. Reading, measuring and annotating stay free, the first two exams you import are free, and the sample exams never count towards that.
