MicroDicom in 44 languages – native speakers wanted

MicroDicom 2026.5 BETA adds 44 interface languages besides English, from Arabic and Bulgarian to Vietnamese and Chinese. Menus, dialogs, tooltips and messages are all translated. On the first start the viewer follows the language of your Windows; you can change it at any time in Help › Language.

Arabic, Hebrew and Persian are shown right to left, with the whole interface mirrored. The medical images themselves are never mirrored.

Apart from Bulgarian, the translations are machine-made and have not yet been reviewed by native speakers. If you spot a wrong term or awkward wording in your language, we would be glad to hear from you. Each language is a single text file, so corrections are easy to make and to send.
