1 You should use your own software and hardware (e.g., a disc publisher) to burn the contents of the autorun package (with the license key file) along with the DICOM study files to the CD/DVD media (or record to USB Flash). RadiAnt DICOM Viewer cannot burn CD/DVDs by itself.
2 The installer size of RadiAnt DICOM Viewer is 7MB; the disk space occupied after installation is 10MB.
3 RadiAnt DICOM Viewer CD/DVD adds 11MB overhead to the CD/DVD (when both 32- and 64-bit versions are included).
4 RadiAnt DICOM Viewer CD/DVD can only run from the CD/DVD discs or USB Flash removable drives and display images stored on the media on which it runs. It cannot be started from your local hard drive. Furthermore, DICOM studies cannot be opened from locations other than removable media the viewer was recorded on.
5 It is not possible to export secondary images obtained using Multiplanar Reconstructions (MPR), 3D Volume Rendering, Fusion, or Time-intensity Curve (TIC) tools to DICOM files.
6 Available with the DCMTK add-on package installed.
7 The series have to belong to the same study.
8 Only available with the 64-bit version of RadiAnt DICOM Viewer. Supported NVIDIA graphics card required.
9 RadiAnt DICOM Viewer and RadiAnt DICOM Viewer CD/DVD are distributed with English and Polish language support. Other translations (Arabic, Brazilian Portuguese, Bulgarian, Chinese, Chinese [Taiwan], Croatian, Czech, Danish, Dutch/Flemish, French, German, Greek, Hungarian, Indonesian, Italian, Japanese, Korean, Mongolian, Norwegian, Persian, Portuguese, Romanian, Russian, Serbian, Slovak, Spanish, Swedish, Turkish, Ukrainian) have been created by the community and are available for download from https://www.radiantviewer.com/translations/.
