sinogram #1

Open RedhouaneBJM opened 3 years ago

RedhouaneBJM commented 3 years ago

Hello,

i'm doing the same simulation as you except for the part "phantoms_meep" where i'm using python instead of C++. I have several fields acquired with different angles, and i would like to know how did you do to calculate the sinogram. are you recording two fields (with and without phantom) for each angle ?.

Thank you

paulmueller commented 3 years ago

Yes, exactly. I divide the field with phantom by the field without phantom (background correction).

RedhouaneBJM commented 3 years ago

after that the divsion with/without how did you calculate the sinogram ?

You can find that code here: https://github.com/RI-imaging/FDTD_sinogram/blob/master/meep_tomo/meep_tomo/extract.py
