  Aims: The main aim of our study is to analyse Electron Beam Profiles like Flatness, Symmetry with 2D Array Detectors. The 2D Array can be used as an alternative device to measure the Electron beam profiles. Introduction: Flatness and symmetry of a radiation beam: The flatness of the beam is defined by the following formula: Flatness (%) = Dmax/Dmin × 100% (1) Where Dmax and Dmin are the maximum and minimum doses respectively within the area. Radiation field symmetry is defined as the maximum ratio of doses at two symmetric points relative to the central axis of the field. Symmetry (%) = [D(x, y)]/[D (-x,-y)] × 100% (2) Methods and Material: The beam symmetry is easily defined and is not very dependent on the depth of measurement. However, the flatness of the beam depends on the size and shape of the measureme.. Read More»
