Configuring and testing imaging filters

You can configure imaging filters individually for any number of supported imaging devices.

Example: You can have different filter settings for the Gendex sensors and the ScanX scanner.

You can also test these filters to see how the new filter settings will affect images that you acquire without having to expose yourself or someone else to X-rays repeatedly.
