Hi everyone

Hi everyone,

Does anyone have syncmlce sample sequence of step and shoot for Elekta. I tried with the sample provided in omega, however, I couldn’t run the test. It will be a great help if anyone kind to share a sample fie. thanks a million.

Hi all

Hi all,

Just a quick question.. Is it possible to restart a run using the egs_chamber code and continue the simulation from the number of histories already completed in the previous run ( like in all the other EGSnrc user-codes ) ?? The option ” irestart = restart ” doesn’t seem to work, so I am wondering how I can do it.. ?

Many thanks,

George

Hi all

Hi all,

I would like to calculate pdd curves for an x-ray beam in water. I have an energy spectrum of the beam, energy (MeV) vs. relative intensity. Can I do this in EGSnrc, any particular such as DOSXYZnrc, BEAMnrc,..? Also, will it be enough to have energy spectrum of the beam will be enough or not to calculate pdd curves?

Kindly,

Rajesh

Hello

Hello,

I’m trying to write a plan for a course that I have to give next semester, so accuracy is very secondary, I’m ready to make a lot of concessions to speed it up 😉

I took the model of linac in EGS++. It is defined as a stack of cones with inscribed geometries for the jaws and mirror for example, which should be very understandable for students who have very limited knowledge of MC. I just prolonged the stack to include the air at the exit of the linac and I place a XYZ geometry made of water to acquire pdds and profiles.

My problem is that when I include that XYZ geometry, the number of the regions in the simulation increase immensely (up to more than 4 000 000 regions), so much that I have the impression the whole linac is voxelised.

Is this possible? Should I use another way to model this? Place everything in a box of air for example and model the linac and the water box separately?

Thanks.
