[Castor-users] Attenuation correction for PET image

[STUTE Simon]

Hi,


I may be wrong but Chang's method is for SPECT.


For PET, you have to compute the attenuation correction factor for each event also, and add this information in the datafile.

Objet : [Castor-users] Attenuation correction for PET image

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
