[Gate-users] How to define the range of HU CT image in code?

[Mery MB]

Dear Gater

I add a phantom to the code but as it is clear I should add the HU of image
to the code too.
I converted DICOM to h33 and I33 for code and I used the following link to
define th HU

http://wiki.opengatecollaboration.org/index.php/Users_Guide:Voxelized_Source_and_Phantom

 # Number of subdivisions
3
# Define the intervals and attach a correlated material
0 10 Air
11 200 Water
201 255 SpineBone

I know all the above definition But for my phantom which have all the
organs, what is the range of HU for organs? How can define the range of HU
Number on CT for my code?
For example the below range: I am not sure the range is correct at all...

7
0 0 Air  false 0 0 0 0.2
0 10 Lung true 0 0 1 0.2
10 1050 Body true 0.3 0.2 0.1 0.2
1050 1150 Muscle true 0.4 0.2 0.4 0.2
1150 1300 Cartilage true 0.2 0.3 0.5 0.2
1300 1600 SpineBone true 0.2 0.1 0.6 0.2
1600 9000 RibBone true 0.1 0.9 0.4 0.2

Best
Mery
