From CT to qCT?

Dear all
Is there an extension that allows to extract segment statistics for known CT calibration parameters?
I would like to extract bone density values instead of HU.

Segment statistics reports results in whatever unit your image contains. If you have a calibration formula then you can easily transform your voxel values according to that, before you compute statistics.

Dr Lasso
Can I ask how the voxel values can be transformed in slicer?
Since I would like to use different formulae, is it possible to apply the different transformations for different voxel values intervals?
Thank you so much for your quick reply.

Yes, you can transform the values any way you want by getting voxel array as a numpy array and then use standard Python functions on that array. See examples in the script repository.

Thanks a lot Dr Lasso
