[Gate-users] Post-doc offer in France

[Irene BUVAT]

Dear Colleagues, 

Please find enclosed a post-doc offer that may be of interest to you or your colleagues. The topic is enhancing an original reconstruction method for PET and assessing its added value with respect to conventional methods for early diagnosis of Alzheimer Disease. 

Best regards,

Objet: Re: [Gate-users] Quadrupoles and dipoles in GATE 

Hello Erik, 

I never used magnetic field in Gate, but it seems that some macros exist to define a global field (/gate/geometry/setMagField). 

If it does not fit your need, you will need to create specific classes in Gate that Geant4 concepts ( http://geant4.web.cern.ch/geant4/G4UsersDocuments/UsersGuides/ForApplicationDeveloper/html/Detector/electroMagneticField.html ). It should not be too difficult. Just think to start from the last version of the Gate source code in the git repository, and start by creating a new branch. 

(To my knowledge, no current plan to implement magnetic field attached to a specific volume in Gate) 

Sincerely, 
David

Hello 

I am a new GATE user, predominantly interested in its radiotherapy applications. My longer term goals are to simulate dose distributions using CT-images, especially with an eye to paediatric patients. Before all that I want to implement a beamline/nozzle. In the 7.0 User's guide, it says: 

"A magnetic field can be defined. It will be attached and thus active in the whole world volume. It is currently not possible to confine the field to another volume." 

Since I want to model quadrupoles and dipoles, I do not want to have a homogeneous, world-wide magnetic field, but rather a number of fields confined to certain volumes. Am I perhaps looking in the wrong place, or is that not possible to model at the moment in GATE? 

If it is not possible at the moment, is there anyone with plans to implement it? 

With regards 
/Erik Almhagen
