> Hi Loic,****
>
> Thanks for your answer. That means with the method I described in the
> previous email, if I use 1 for the intensity and skip (/gate/source/PBS/SetSpotIntensityAsNbProtons
> true ) then I should be able to write the results per spot in output file.
> Is that correct?****
>
> Could you please send me the address of wiki? For the pencil beam I found
> only a short description in the wiki.****
>
> Thanks again****

> Hi,****
>
>  ****
>
> So, just to be clear in what we are talking about:****
>
> - spot canning is a treatment technique in which you scan a pencil beam***
> *
>
> - a treatment is made of one or several field of treatment****
>
> - a field is made of different energy layers, creating a kind of "SOBP"***
> *
>
> - a layer is made of spots****
>
> - each spot has a position X, Y, an energy E and an intensity (or
> weight) given in MU or number of protons (/gate/source/PBS/SetSpotIntensityAsNbProtons
> true )****
>
>  ****
>
> The delivery of a field is "random", in the sense that each spot of the
> field is delivered according to its intensity: a spot with intensity 2 will
> be sampled 2 times more frequently that a spot with intensity 1 ( see wiki
> documentation).****
>
>  ****
>
> So either you can modify the source code, so that the field delivery is
> not random, or you can run simulations spot by spot, simply by modifying
> your [plan_description_file] according to your needs.****
>
> This second option seems to me the better option.****
