"Low signal level" parameter has replaced the "Air Threshold" parameter. The new parameter is quasi-constant ( in [5,10] range) and is independent of the volume content.
Separated the notion of Air Threshold and the Signal-to-Gradient ration. They produce separate masks now. Air-Threshold can be defined very approximately now and completely automatically without User Input, as it is mostly used cosmetically to make the resulting volume to look without Air amplification. Another component, the areas of the low Signal-to-Gradient ratio are excluded and this improves the Non-Uniformity measures substantially.
For the reference image, BPD-7T, with the same parameters the measures for
