One folder entails a simple phantom of a K-insert in a C-matrix.
Run ./K_in_C/K_in_C_DECT.py for DECT material decomposition with Gauss-Newton optimization.
A direct reconstruction of the simualted data can also be performed using ./K_in_C/K_in_C_reco2D.py
Another folder entails a simple phantom of a WM/GM-phantom, inside a CSF-matrix surrounded by 1 mm bone.
Run ./WMGM/WMGM_DECT_reco.py for DECT material decomposition with Gauss-Newton optimization.
A direct reconstruction of the simualted data can also be performed using ./WMGM/WMGM_cube_phantom_2Dreco.py. To switch between the different phantoms, simply change phantom_1 to phantom_2 in the file definition.
