[Gate-users] Materials for CT (FFDA) simulation

[Shiras Abdurahman]

Hi,

I am using FFDA for CT projection simulation from voxelized phantoms. I
utilize ICRP_HUmaterials.db for material description and a separate text
file called cylinder.mat to map HU to material
(/gate/patient/geometry/setHUToMaterialFile). The content of the text file
is given below:
-10 10 Vacuum
10   1010 G4_WATER
1010 2210 G4_BONE_COMPACT_ICRU
For a volume which contains air, water, and bone, I set the corresponding
voxels with HU values 0, 1000 and 2000. Could you please confirm whether
these values are correct? I would also like to add objects which
represent Titanium implants. So what should I do in this regard?

With regards,
Shiras
