1 You need your own hardware and software (e.g. a disc publisher) to record the contents of the autorun package archive along with the DICOM study to the CD/DVD disc. RadiAnt DICOM Viewer cannot record CD/DVD discs by itself.
2 The installer size of RadiAnt DICOM Viewer is 3MB; the disk space occupied after installation: 5MB. RadiAnt DICOM Viewer CD/DVD adds 7MB overhead to the CD/DVD disc (both 32 and 64-bit versions are included).
3 RadiAnt DICOM Viewer CD/DVD can open DICOM files that were recorded on the same CD/DVD disc or USB drive. It cannot read other discs or USB drives recorded without the RadiAnt DICOM Viewer CD/DVD autorun package.
4 Export to DICOM files is unavailable for secondary images obtained with the use of either MPR (Multiplanar Reconstructions), 3D Volume Rendering, Fusion, or TIC (Time-intensity curve) tools.
5 The series have to belong to the same study.
6 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) are created by community and are available for download from www.radiantviewer.com/translations.php. Not all translations are updated for the newest version of the viewer.
7 Available only in 64-bit version of RadiAnt DICOM Viewer. Supported NVIDIA graphics card required.
