A graphical user interface for calculation of 3D dose distribution using Monte Carlo simulations
The input parameters for the uniform isotropically radiating parallelepiped: Similar to source 1, a uxer coordinate system is set up at the isocenter, xiso, yiso, ziso. If this still results in many restarts because of many particles missing the geometry or beyond beam fieldthen re-run the simulation with NRCYCL set manually to: Note, this option disabled, but must enter blank record for compatibility. There is also a graphical user interface GUI which allows input? This option increases the efficiency of dose caluclations more than photon forcing.
There is a possibility that, even with the automatically calculated value of NRCYCL, the phase space source dosyznrc restart. Do mortran compilation only, leaving behind the Fortran file dosxyznrc.
The exact value of the global PCUT is not critical in the sense that low values do not take much more time. This is taken useg of automatically if you are using the GUI to set this parameter.
This will generate a binary. For more information related to phase-space sources, see the section on phase-space? These extensions are either no longer used or are not supported and, thus, these authors are no longer included as authors of the users manual. Note that these settings of n split are higher than those calculated using the rule of thumb given in the paragraph above.
In order to reduce the systematic uncertainties due to a small data set, DOSXYZnrc can redistribute the phase-space particles as long as the simulated linear accelerator geometry is symmetric, and the treatment?
Bound Compton scattering may also be turned on in selected regions o? Note that the e? If any of the? Recall that when entering the input parameter the beam code, specifying the BEAM simulation to use, you simply use BEAM accelname, omitting the lib pre? Otherwise, leave it Off. If you develop extensions, why not share them with your colleagues? These fat photons may compromise dose statistics.
The angles thetax and thetay are relative to the positive x- and y-axes respectively, while thetaz is measured relative to the negative cosxyznrc. NRCYCL is not automatically calculated if you are only using the positrons in the phase space source or if you are selecting a sub-set of the phase space source based on LATCH settings. This is used in conjunction with photon splitting input variable n split, see Section 8. The code includes a restart facility and can be run on parallel computing platforms.
Input parameters for source 9 are: This has been found to give accurate dose results over all energies and maximum allowed step lengths input variable SMAX, see paragraph below. Similar to bound Compton scattering, photoelectron angular sampling can be turned on or o?
If this input is set to Off the defaultthen the Klein-Nishina formula is used to determine crosssections for Compton scattering. Particles from the phase space which are initially outside both the phantom and surrounding region are terminated immediately.
Dosxyanrc graphical user interface facilitates creation of these input?
Inputs for source 10 are: Rayleigh scattering can be turned on or o? A skin depth of 3 elastic mean free paths has been found to give peak e? Basically, jobs are controlled by a job control? The incident angles theta and phi are de? The user should also input the phase-space? It is linked to ctcreate. In the case of an IAEA-format phase space source, the full name of the phase space data.
Every voxel volume element can have di?
Jobs run until there are no histories remaining in the job control? The NRC setting is only of interest at low energies, where these cross-sections take into account assymmetry in the positron-electron energy distribution. The default setting of medsur is 0, indicating the surrounding region yser vacuum. For accurate electron transport with default EGSnrc electron step algorithm see section 9.
Rogers Ionizing Radiation Standards Nation. It must be a working input file and must be set up to write a phase space file at a single scoring plane. The possible settings of enflag are: The following describes some?
