Simulation Efficiency and an Introduction to Variance Reduction Methods
نویسنده
چکیده
In these notes we discuss the efficiency of a Monte-Carlo estimator. This naturally leads to the search for more efficient estimators and towards this end we describe some simple variance reduction techniques. In particular, we describe common random numbers, control variates, antithetic Variates and conditional Monte-Carlo, all of which are designed to reduce the variance of our Monte-Carlo estimators. We will defer a discussion of stratified sampling and importance sampling until the next set of lecture notes.

Background: Radiotherapy is an important technique of cancer treatment using ionizing radiation. The determination of total dose in reference conditions is an important contribution to uncertainty that could achieve 2%. The source of this uncertainty comes from cavity theory that relates the in-air cavity dose and the dose to water. These correction factors are determined from Monte Carlo calcu...

Background: Various variance reduction techniques such as forced detection (FD) have been implemented in Monte Carlo (MC) simulation of nuclear medicine in an effort to decrease the simulation time while keeping accuracy. However most of these techniques still result in very long MC simulation times for being implemented into routine use. Materials and Methods: Convolution-based force...

This paper presents the study on the effect of detector type in estimating gamma rays buildup factor. In this regard, the flux buildup factors of gamma rays emitted by an isotropic point 60Co source in mean energy 1.253 MeV was evaluated after passing through the Pb, W, Zn, and Ti sample in thickness of 1-5 cm by MCNPX. Four common detector types in simulation of measurement was defined to esti...
