[Castor-users] attenuation correction and normalization

[Hadi Rezaei]

Dear CASToR users
I simulated an IEC NEMA phantom on a PET using GATE and reconstructed it
using CASTOR without any correction (random, scatter, attenuation and
normalization). The reconstructed image was undesirable. I found that for
random and scatter correction I can write "-t" on
the castor-GATERootToCastor to convert only trues (is it right?). But, how
can I perform the attenuation correction (and also normalization)?
I used bellow commands for convert to CASTOR and reconstructed it.
 ./castor-GATERootToCastor -i output.root -m mymacfile.mac -o IEC -s IEC
-geo -k
./castor-recon -df IEC_df.Cdh -dout IEC -opti MLEM -it 10:20 -th 40 -dim
512,512,1655 -fov 600,600,1940
I attached the reconstructed image here.  I would therefore appreciate it
if anyone could help me to apply any correction on it.
Best regards
Hadi
