[Gate-users] REAL-PHANTOM

[Lorena Vázquez Canelas]

Hi Gaters,
I
 have tried to simulate a Hoffman brain (a voxelized phantom) with my 
PET and finally i can reconstruct the image with STIR later.
The only thing i could do (in root) is what i show in the picture (.jpg):
              


The values that i used in ascii archives are the following: 
- Attenuation_range.dat:
  4
  0     0     Air         false 0.0  0.0  0.0  0.2
  4     4     Water       true 1.0  0.0  0.0  0.2
  5     5     Water       true 0.0  1.0  0.0  0.2
  14    15    Water       true 0.0  0.0  1.0  0.2
- Activity_range.dat:
3
4   4    10
5   5    30
14  15   50

My
 question is: How i can know what kind of tissue to use for my phantom 
is as realistic as possible?  I am a physicist, not a doctor!
Thanks in advance
