Definition of LSO and BGO

Is there any notes for me to learn for simulating Nuclear Medicine modalities such SPECT-CT or PET-CT. I tried to create but how can i define the LSO and BGO in material. It seems keep showing the error in geometry part as no material LSO or BGO in material.

Dear @zzat.aseri,

To learn how to define material in Fluka, have a look at the material lecture from the last course.

Open Flair ----> go to top right drop-down—> Materials----> In Search tab put LSO or BGO—> Enter–> Select the material----> Click on “to input”. The material will be added to your input file.
