Linac photon beam fine-tuning in PRIMO using the gamma-index analysis toolkit.BACKGROUND
 The objective of this study is to utilize the results of the gamma-index analysis toolkit embedded inside the windows-based PRIMO software package to yield a truncated linac photon beam fine-tuning process.


 Using PRIMO version 0.1.5.1307, a Varian Clinac 2100 is simulated at two nominal energy configurations of 6 MV and 10 MV for varying number of histories from 106 to more than 108.  In the matter of fine-tuning a linac to conform with measurements, this characteristic is exploited directly by the PRIMO software package.  PRIMO is an automated, self-contained and full Monte Carlo linac simulator and dose calculator.

 It embeds the gamma-index analysis toolkit which can be used to determine all the parameters of the initial electron beam configuration at relatively lower number of histories before the full simulation is run at very high statistics.
