Usage:

ctac_to_mu_values -o output_filename -i input_volume -j slope_filename -m manufacturer_name [-v kilovoltage_peak] -k
target_photon_energy 

Default value for tube voltage is 120 kV. For PET, the target_photon_energy has to be 511.

This convert HU to mu-values using a piece-wise linear curve.

Warning

This utility currently does not implement post-filtering to PET resolution, nor resampling to the PET voxel-size.
