About setting threshold values

[Rudeguy1]

Hi there,
This is a very meaningful research, and I have some questions when studying.
HU_thred = (-150.0 - hu_min) / (hu_max - hu_min)
How is the value of this formula determined? Can the value(-150.0) used to focus on different organs be a same value? Or choose the window width and window level of different organs.
Look forward to your reply

best wish

lung_min=0.7,
lung_max=0.15
Is this value obtained through statistical calculation? and Is it through the formula above？

lung_max=0.15,

Is there a problem setting the value here
