[Gate-users] Dose Actor

[meryem fiak]

Dear all,

I'm a beginner in gate and i need some , I use gate in radiation therapy in
order to calculate pdd and profile dose in a water tank and compare them
with  measurements.

I do not know what method I should use,


I have to calculate the PDD and profile dose  throughout  the water thank
(60*60*60 cm) and at 10 cm depth. The volume of the ionization chamber is
0.8 cm3.

/gate/actor/addActor                     DoseActor  dose3d
/gate/actor/dose3d/save                  output/dose3D.hdr
/gate/actor/dose3d/attachTo              waterbox
/gate/actor/dose3d/stepHitType           random
/gate/actor/dose3d/setPosition           0 0 0 cm
/gate/actor/dose3d/setSize               60 60 60 cm
/gate/actor/dose3d/setResolution         30 30 300
#/gate/actor/dose3d/saveEveryNSeconds     60
/gate/actor/dose3d/enableEdep            true
/gate/actor/dose3d/enableDose            true


This method is valid or not?, and if i want to calculate to 10 cm depth, i
can just change the position to     /gate/actor/dose3d/setPosition
0 0 10 cm



I use another method where I divide the water tank to dosels with a step of
0.5 cm (see figure below), vertical dosels for PDD and horizontal for dose
profile.

Among the two methods where is  the most valid method to compare with the
measurement.



*Thank  you for any help*
