[Gate-users] Voxelized Phantom

[Grevillot Loic]

Hello,


1.       For dose scoring, you do not need to voxelize the geometry, you just need to add a DoseActor and specify the scoring resolution (http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.2:Readout_parameters_for_Radiotherapy_applications:_Actors#Dose_measurement).

2.       For active scanning delivery, you can use the TPSPencilBeamSource with as many beams as you want (http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.2:Source#TPS_Pencil_Beam_source).

3.       The dose is extracted through the dose Actor (see 1) in Gy.

Please keep going with example to get familiar with these different features.

Best,
Loïc

Subject: [Gate-users] Voxelized Phantom

Dears All,

I hope you are well. I am a new user of Gate working on PhD project  (charged particles for radiotherapy application). There are many useful examples in Gate (many thanks for this) and I have some questions in this regards as follows:

1- If I have a 30*30*30 water box phantom, I want to calculate PDD and dose profile what is the best choice to voxelize it? Is NPV technique suitable here for the whole phantom voxelization?

2- How can I run a simulation with 4 beam (box technique) with different beam directions on the box?

3- After finishing voxelization and running the simulation, how can I calculate the the dose (Gy/mass) or Gy/voxel?

I would be grateful for any help.
Kind regards,

Awad
