[Castor-users] Attenuation correction for PET image

[김연경]

Dear CASToR users

I obtained the image of the GATE simulation data using the castor program.

I would like to ask the confusing part of applying the attenuation
correction to the acquired image. The data is list mode.

if I enter the same image as the phantom size with attenuation coefficient
value into the -atn option, will the attenuation factor be calculated
within the caster program's code and corrected for the image?

If the method described above is correct, does the program use the method
of Chang's multiplicative?

Any help I would really appreciate it.

Best regards
