[Gate-users] Source definition in STL complex geometry

[Ashok Tiwari]

Hi Josh, 

I was also thinking in the similar way i.e, create a source that is slightly larger than STL file’s approximate size. 

Which command is best, confine or attach in source definition? I’m using attachTo instead of ../gps/confine  [volume].

Another thing: In my STL phantom, I’ve added lungs cavity and some spheres (lesions). I want to define a lung cavity so that it mimics the lung. In real phantoms styrofoam is added to mimic the lung. Any thoughts on this matter?

Thank you.
