Hello;

          I am not sure about it, but I think fo-dicom does not support non linear LUTs.

From memory, non-linier luts work fine, I have a number of Mamo's with non-linier luts that work fine, you can also approximate a linier lut from a not linier lut.

So I can't quite remember if fo already did this or if this was a modification that was required, I'd have to go look at my code, what's the issue your having?

Hi Chris,

I want to find the widow width and level from the VOILUT data. Since the image has no window width and center, I am trying if i can compute them using the VOILUT data.

Are you able to post the file?

as thers not enough data in your pic see the following link

http://dicomlookup.com/lookup.asp?sw=Tnumber&q=(0028,3002)

this looks like its a modality lut not a softcopy presentation lut...
