| The doses were measured at the depth of 10 cm and at the maximum dose dmax for two energies 6 MV photon and 10 MV photon on Elekta machine. Measuring dose was done by using only two points and comparing the results with percentage depth dose (PDD) for the depth dose curve for both energies. In addition the doses were obtained by using three methods of detectors to measure the dose by using the ion chamber, Thermo luminescence, and films. The results obtained for three measurements agreed within 2% for 6 MV photon and 3% for 10 MV photon by using three different detectors in the clinic. Therefore, these detectors are stable and reliable to be used in clinical applications. |
