[Castor-users] Attenuation correction for PET image

[김연경]

Dear Thibaut

Hi!

Thank you for your answer.
Sorry, The damping factor in Q2 is the wrong attenuation factor. So, I
wrote the question again below.

Q1. If you provide an image filled with only 'attenuation coefficient
value' after '-atn', is it right for the CASToR program to calculate the
'attenuation factor' according to the distance or position within the
phantom?
      Or do I have to provide an image that included calculated attenuation
factors for each position of the phantom?


Best regard
