Evaluation of latent variances in Monte Carlo dose calculations with varian TrueBeam photon phase-spaces used as a particle source.

Conclusions:</b> In order to achieve sub-percent latent variance in open 10x10 cm<sup>2</sup> field MC simulations single PSF can be used, whereas for small SRS fields more PSFs would have to be summed.
