[Gate-users] TPS pencil beam source

[Elia Alessio]

Dear Zhang Hui,

as reported in the wiki, the plan description file contains information about the plan, like number of fields, gantry angle for each field, energy of each layer from each field, number of spot in each layer, spot description (position in x- and y- direction at isocenter and intensity) for each spot from each layer. Some of the parameters implemented in the plan description file are not used directly by the Gate source code as either not useful for the simulation or not implemented yet (like for example the PatientSupportAngle). There are a lot of parameters described in this file and all of them are coming from typical dicom RTplan file. For a further description about them maybe you can have a look to some dicom RTplan file (they are standard type therefore the tags are always the same) and look at the description of the parameters directly from there.

As a general comment, you are right, at the moment a detailed description of what is read and what is not (parameter by parameter) is actually missing in the wiki. The description about the source_description_file could be also improved. Maybe you can specify what is not exactly clear to you so far?


Hope it can help!

Cheers,
Alessio

Subject: [Gate-users] TPS pencil beam source

Dear Gaters,
    I'm using TPS pencil beam source to simulate  active beam scanning delivery techniques with carbon ion. I'm  confused about  the descriptions of source_description_file and plan_description_file in users guide. The descriptions are too brief especially about plan_description_file. In example/example_Radiotherapy/example5/data/PlanDescriptionToGATE.txt, there are many comments with 'CURRENTLY THIS VALUE IS NOT USED'. Dose anyone know  the detail description about them? Thank you!
