[Gate-users] Dose Actor Voxels?

[Matthew Strugari]

Hi Josh,


I am not entirely familiar on the behaviour of the doseActor, but it appears that the output dose is given as the dose per voxel. Hence, the same dose is deposited after integration in each case.

All,



Can you explain how the voxel size and number impacts the calculated dose by the doseActor?

I have simulated a 1 liter cube of water containing 0.01 mCi of 18F positrons. When I enable the doseActor using 1000 voxels each 1cm^3, I get a total of 2.43E-05 Gy. However, if I enable the doseActor using only 1 voxel of size 10cm^3, I get a dose of 2.43E-02 Gy.



I get the same total energy deposited no matter the voxel size and number, why not dose?
