[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 --à  60 Events

                                               =20--à  72 Events

                                               =100
--à
 68 Events

                                             =200 --à  59 Events

Is what is normal to found this
result and the scatter =0

Can you help me

 
Best regards  
 Mariam
