[Gate-users] Spot scanning using Pencil beam

[Joulaeizadeh, (L) , Mrs]

Hi,
Is there really not a way to separate the dose pattern of different spots in the output?

In my simulation, if I for example simulate 100 protons for two spot scanning and change the name of the output file after every 50 protons simulated, still in every output file I see a mixture of dose pattern from both spots.
In the plan description file, I define the spot position and use the weight of 50 as the number of protons should be simulated for that spot. In addition in the main macro I use

/gate/source/PBS/SetSpotIntensityAsNbProtons true

Where I'm making mistake to your opinion?

p.s.: Loic it's impractical to run the simulation for every spot separately even if I use the command "SetNotAllowedFielsID 1".

Thanks
Leila

I do not understand exactly your issues, but what I know is that if you run one simulation for one spot, you have the dose for this spot.
I you do so for each spot, you will have a different output for each spot, which is I think answer your first questions.
You can then sum-up all doses for all spots together if you like.
If you wish to obtain directly one output per spot in a single simulation, you have to modify the source code I guess.

Hope this help,

Loïc

Hi Loic,
I need to run the simulation of all the spots once since I need to use different output files of one simulation to later calculate the heat transport by time in a water phantom.
Any other idea to solve the problem?

You may try to run one simulation for the first spot and another for the second spot, or to separate them per field, using this command:

#/gate/source/PBS/setNotAllowedFieldID 1

Dear Gate-Users,
I would like to scan two separate spots using a proton pencil beam. I would like to scan the first spot, write the dose in a first output file (can be root file), then scan the second spot and write the dose in the second output file.

The problem is that one dose file is not specified to one spot and in every dose file I see the information of two spots.

Does anyone know how can I have separate output per separate spot?

My planning file and main macro are attached to this email in case you would like to have a look.

Any help would be appreciated.

Leila
