User manual
by RadiAnt on July 1, 2013
When we started developing RadiAnt DICOM Viewer we had one goal in mind, to keep it as simple as possible. This is probably why we kept on procrastinating on writing a user manual for our software.

Well, that is, until today. Because today we are presenting you a complete user guide which hopefully will help you get the most out of RadiAnt DICOM Viewer.

The manual is available as a searchable online help or a PDF file for downloading and printing.

Enjoy the reading!
