[Gate-users] Fluence actor information

[Anders Garpebring]

Dear Gate users,

Can someone explain the fluence actor a bit more. Is there some more documentation than in the gate manual? Some specific questions:


1.      If I use the command "setSize" will the image be centered around the center of the mother volume and have the physical size I specify?

2.      What is meaning of enableScatter? Is it that scattered radiation is be counted too? For instance when radiation first pass through a pixel and then is scattered back through the pixel

3.      In the gate documentation it says that each (new) particle passing a volume is counted. What does this mean? Shouldn't one count all particles entering?

4.      Counting particles entering a pixel is not a good way to measure fluence since the fluence become a function of the pixel geometry. Is this somehow compensated for? If not are there some more advanced fluence actor available? For instance one that is based on track length.
Best,
Anders
