Hi Everybody

Hi Everybody,

I am trying to configurate the MLC’s.

Nevertheless, I can’t find the file where I could modify settings such as this one : (MLCQ parameters)

A question about photonuclear attenuation:

A question about photonuclear attenuation:

Is it OFF by default in the latest version of EGSnrc? I don’t see any documentation for it in PIRS701.

The only information I could find is in a report by Ali and Rogers, http://physics.carleton.ca/sites/default/files/clrp/databases/photonuclear/Ali_et_al_clrp_12_01.pdf

Curious to know the latest development! Thanks.

Hello everybody

Hello everybody,

I have tried to install this software but I find this error in the configuration process.

Can someone of you, please help me?

Thank you

Will disable now the availability of a C compiler.

If you want to try to make the new parallel processing implementation in

cavrznrc and dosrznrc work,

1. Go to $machine_mortran_dir

2. Edit egs_c_utils.h and egs_c_utils.c to make them compile with your

C compiler

3. Put

REPLACE {$HAVE_C_COMPILER(#);} WITH {{EMIT;{P1}define HAVE_C_COMPILER};}

in machine.macros

4. Put

$HAVE_C_COMPILER(#);

near the beginning of your user code.

5. If your compiler requires some unusual options, include directives, etc.,

change the variable C_FLAGS in the spec file $conf_file in the

$HEN_HOUSE/specs/ directory.

Hi everyone

Hi everyone,

what is the relationship between the “ncase” and “activity” of an EGS_RadionuclideSource with to “decay time”?

for example; ncase = 1e6, activity = 1e6. Since the activity is in Bq = disintegration/sec; is it correct to say I am simulating only 1 sec of my source since get(Fluence) = ncase for my simulations.

I really don’t understand the equation;

time += -log(1-u) / activity;

Thanks very much in advance

Dear egs_cbct Users

Dear egs_cbct Users,

I have been asked that “What is the detector? Are you collecting photons in a square “phase space” simulating the detector. “. Would you please tell me what is the meaning of square “phase space”. Does square “phase space” represent the ideal detector?

Thank you

Hi all

Hi all,

I would like to understand how ctcreate compose new voxels from original ones. I didn’t find the explanation in pirs794-dosxyznrc, so I tried to get familiar with the ctcreate.mortran source code. I am attaching the formulas I created according the source code, but I am not sure if they are correct, i.e. I do not believe myself I have resolved the code properly. What do you think? The formulas are set to be ok for the 2-D example of 4×4 array as represented below.
