Dear,  
Is there any way to adjust the CBCT parameters: Contrast, Sharpness in a similar way done in Romexis “Histogram”?  
I know there is a function as I attach here, but you wont see the values.

These are basic functions of Slicer. The documentation is really useful if you haven’t checked that.

Adjusting window-level:

Volumes module:
