In this work we present an algorithm based on the simulated annealing (SA) method for electron beam spectrum reconstruction from central axis PDD data. We use a simulated beam in order to assess the accuracy of the method, and compare it with others usually employed. We found that our modified SA algorithm produced excellent reconstructed PDDs and beam(More)
In the present work, phase-space data files (phsp) provided by the International Atomic Energy Agency (IAEA) for different accelerators were used in order to develop a Virtual Source Model (VSM) for clinical photon beams. Spectral energy distributions extracted from supplied phsp files were used to define the radiation pattern of a virtual extended source(More)
In a previous work, phase-space data files (phsp) provided by the International Atomic Energy Agency (IAEA) were used to develop a hybrid virtual source model (VSM) for clinical photon beams. Very good agreement with dosimetric measurements performed on linear accelerators was obtained for field sizes up to 15×15cm(2). In the present work we extend the VSM(More)
