Estimation of the focal spot size and shape for a medical linear accelerator by Monte Carlo simulation.

Lilie L W Wang1, Konrad Leszczynski.   

Abstract

The focal spot size and shape of a medical linac are important parameters that determine the dose profiles, especially in the penumbral region. A relationship between the focal spot size and the dose profile penumbra has been studied and established from simulation results of the EGSnrc Monte Carlo code. A simple method is proposed to estimate the size and the shape of a linac's focal spot from the measured dose profile data.
