Special issues for Rotational IMRT: Discretized Arc vs. Continuous Arc Dose Calculation

Most algorithms calculate the dose of an Arc as sum of segment dose contributions from discrete beam angles

Monte Carlo: Beam angle can be treated as additional random variable! → simulation of the rotating, dynamically modulated beam without discretization of the motion
