Algorithmical Applications in the XiO Treatment Plan Based on Dosimetric Measurements

The beam modeling of the linear accelerator is performed based on dosimetric measurements by including the data obtained for the absorbed dose in water at a depth of 10cm (D10), percent depth doses, and geometric symmetry of the fields. The results obtained for photon beams with the energy 6MV and 18MV are placed in a database of the treatment planning system (XiO). Then, it becomes a reference system for modeling the photonic beams with high energy and creating patient treatment plans. The field modeling and calculation of the dose that should be given to the patient are done by precise dosimetric measurements.
