None Call for input to Geant4 Collaboration Workshop on medical physics requirements 

Forum: Medical Applications
Date: 15 Sep, 2013
From: Joseph Perl <Joseph Perl>

Dear Geant4 Medical Physics Users,

I have been asked to present a 15-minute talk on requirements from the Medical User community at the upcoming annual Geant4 collaboration workshop.

As I have in the past, I will use this time to remind my Geant4 colleagues of the wide variation in kinds of medical physics applications, from linac and brachytherapy studies, to proton and ion therapy, to nuclear medicine and medical imaging.

I will omit discussion of the Geant4-DNA side of things, as Sebastien Incerti has a separate talk on that domain.

I will mention our desire for:
 - better ways to import CAD designs and to handle DICOM I/O.
 - increased accuracy in clinical x-ray and electrons (to close the small but measurable accuracy gap between Geant4 and EGS in Bremsstrahlung and large angle electron scattering).
 - increased speed in all of our computations.
 - better physics in prompt gamma emission for proton therapy.

Beyond these issues, are there others that you wish me to bring to the collaboration's attention at this workshop? Please either write to me personally or post to this forum, whichever you prefer. The talk will be September 23rd. I welcome suggestions right up to the last minute.

Best Regards,

Joseph Perl
