[Gate-users] problem with voxelez the phantom

[mariam zoubair]

Dear Gate users

 
I voxelez the phantom for CT image I run the calculation
with a point source (type is backtoback). I found 60 events and 0 scatters it
is for a 512 x512 image I did a test with the same image but with size 32 x 32
I found 72.

 

I increase slice thickness (pixels):



For slice thickness (pixels) =2     I found 60 Events

                                       =20 I found   72 Events

                                       =100
I found 68 Events

                                      =200 I found 59 Events



Is what is normal to found this
result and the scatter =0
Can you help me

 
Best regards  
 Mariam
