Phase-space database for external beam radiotherapy
IAEA NAPC Nuclear Data Section
IAEA NAHU Dosimetry and Medical Radiation Physics Section
Objective: To build a database and disseminate representative
phase-space data of accelerators and Co-60 units used in medical radiotherapy by compiling existing data that have been properly validated.
How to produce and submit phase-space data: The IAEA phsp format was designed to cover
both phase-space files and event generators
phsp contents). We have implemented
the IAEA phsp format in a set of read/write routines
(Updated: September 2013, see
readme file). Native IAEA phsp format is available in EGSnrc and PENELOPE Monte Carlo codes.
Geant4 interface to use the native IAEA phsp format is also available.
Unfortunately, MCNP does not have a native implementation of the IAEA format.
A generic converter from IAEA to ASCII is also available as iaea2ascii.zip.
Once the validated phsp data is produced and documentation is published,
you may submit your phsp for review using the upload link here.
How to download phase-space data: You have to select a phsp data type
among Co-60 source, linac electron or
linac photon phsps. For photon and electron PHSPs you may download the header
first to decide which data you want to retrieve. Once decided you should download the PHSP data from the corresponding
sub-directory. Please note that the first time access to the selected subdirectory could be slow.
Both the PHSP data and header should be present for the PHSP data to be accesible !
In exceptional cases, you may request
a DVD copy of the desired phsp.
