Open DICOM files, a folder or a ZIP from a CD and look at them right here: scroll through CT and MRI, adjust contrast, zoom and measure. Your files stay on your computer.

Drop .dcm files, a whole folder or a ZIP onto the viewer, or use Open files / Open a folder. A patient CD usually has a DICOM folder: open that folder and every image inside is found, however deep it sits.
Images are grouped the way the scanner recorded them: by patient, by study and by series, in slice order. Click a thumbnail to open that series. Reports and other non-image objects are listed but not drawn.
Use the mouse wheel or the slider to move through the slices. Drag with Contrast to change brightness and contrast, or pick a preset such as Brain, Lung or Bone on a CT. Right-drag zooms, middle-drag pans.
Draw a length, an angle or an area. Measurements are in millimetres when the image records its pixel size. Save picture downloads a PNG of what is on screen, with your measurements drawn on it.
Files are read by your browser on your computer. No upload, no account, no copy kept anywhere. Close the tab and they are gone from the page.
Open hundreds of files at once. They are sorted into patient, study and series, and each series is ordered by instance number and slice position, as the scanner meant them to be read.
Uncompressed, JPEG baseline and lossless, JPEG-LS, JPEG 2000, HTJ2K and RLE, in greyscale and colour, single images and multi-frame loops.
Lengths, angles and areas use the pixel size in the file. On an X-ray that gives only the detector size, the label says so, because the anatomy is magnified; without any pixel size, measurements are shown in pixels, not millimetres.
Open the tag list to see the full header of the image on screen, with standard names, searchable by name, tag number or value.
One finger scrolls the slices, two fingers zoom and pan, and a double tap fits the image again. Nothing to install.
Your clinic or hospital gave you a CD or a download of your scan, and the viewer on the disc will not run on your computer, or there is no CD drive at all. Copy the folder off the disc, or open the ZIP, and look at the images here.
You are a vet, a dentist or a physiotherapist who receives studies from another practice and wants a quick look before the appointment, on whatever computer is in front of you, without installing software or creating an account.
You build or test imaging software and need to check what a file actually contains: its tags, its transfer syntax, how its frames are ordered, whether it decodes.
This viewer is for viewing and sharing. It is not a diagnostic device and is not intended for diagnosis; a qualified clinician reads every image. To keep scans safe and send them to patients and doctors as a link, see BigMind Medical.
No. The files are read by your browser on your own computer, and the images are decoded there too. Nothing is sent to Genie9 or anyone else, and nothing is kept after you close the page.
Copy the CD to your computer (or open it directly), then use Open a folder and choose the CD’s top folder. The viewer looks through every subfolder, skips the CD’s own viewer program and index file, and opens the images it finds.
DICOM Part 10 files (usually .dcm, or files with no extension), whole folders, and ZIP files containing them. It decodes uncompressed, JPEG, JPEG-LS, JPEG 2000, HTJ2K and RLE images. Reports, presentation states and documents are listed but not drawn.
They use the pixel size recorded in the file, and the viewer tells you when that is uncertain: on many X-rays the recorded size is at the detector, so anatomy reads 5–15% larger, and some images record no size at all, in which case measurements are in pixels. This tool is for viewing, not for diagnosis or treatment decisions.
No. This viewer is not a medical device and is not intended for diagnosis. A qualified clinician should read every image on equipment and software approved for that purpose.
There is no set limit; it depends on your computer’s memory. A few hundred CT or MRI slices open comfortably on an ordinary laptop. Very large studies open too, but take longer to read.
Save picture downloads a PNG of the image on screen, measurements included, named by modality, date and slice rather than by file name. To keep whole studies and send them to a patient or a doctor as a secure link, use BigMind Medical.
