PRACTICAL GUIDES · RESEARCH & EDUCATION
Step-by-step guides to the jobs people bring to a DICOM viewer: opening a study, putting images on a slide, fixing tags, exporting pictures and movies, sharing a de-identified copy and preparing NIfTI volumes for research tools. Each step names the app’s own buttons and menus, checked against OmniDICOM 1.1.6, and works the same on Mac and Windows unless it says otherwise.
Put one CT or MRI image, or a whole multi-panel figure labelled A, B, C, onto a slide by copy and paste instead of a screenshot. The picture is drawn at 2400 or 3600 pixels, and patient identifiers stay off it unless you add them.
Every plan and the trial; trial copies carry a watermark strip below the picture.
From the installer to your first study on an Apple silicon Mac: open a folder or a disc with its DICOMDIR, choose a series and scroll through it, and make .dcm files open from Finder.
Apple silicon, macOS 13 or later.
Correct a series description or a research ID in the DICOM tags and save it across the series; which values can be edited, and why Save Changes can be greyed out.
Basic, Professional and the trial.
Turn images into JPEG or PNG files and cine runs into MP4 movies, choosing the scope, the image size and the corner text before you export.
Every plan; trial exports carry a watermark.
Make a copy for a collaborating lab or a teaching file under the DICOM PS3.15 Basic Profile, with new UIDs and shifted dates, and see what the copy keeps, including text burned into the images.
Basic, Professional and the trial.
Save a CT or MR series as one .nii.gz volume in its original values (HU for CT), with its orientation, for segmentation, labelling and analysis tools, without the command line.
Basic, Professional and the trial.
Reduce the noise of a CT series on your own computer with Denoise, compare it with the original and see which tools read the denoised values.
Professional, included in the 14-day trial.
Pages on the viewer itself, by platform and by kind of study:
No card required to start a trial. After the trial, studies keep opening in five-minute sessions and image exports are watermarked; a Basic or Professional licence removes those limits.
