Planning
Osirix & Horos
The KYON Calibration and Template Plugins are intended for use with Osirix 7.0 http://www.osirix-viewer.com/ and Horos – https://www.horosproject.org/.
I would recommend that you try Horos because the free version is more user-friendly and does not include the “not for medical use” warnings. Horos and Osirix look and function exactly the same in all other respects.
The latest version of the plugin includes: TTA, THR, ALPS, PAUL, PGR, TPLO, and TTA-2.
The KYON Plugins are available to KYON clients for free.
How To Download & Install the Plugin:
Steps:
1. Download the KYON Osirix Plugin HERE This version has been tested in Osirix 7.0 Lite, MD and Horos 2.0.0.
2. Click to Open the Downloaded .Zip file.
3. Open each plugin and follow the installation instructions.
4. Restart Osirix after installing each plugin.
5. The Plugins will be available under Plugins >> ROI Tools.
