Caracteriza？？o dosimétrica de feixes de fótons com detector de diamante

objective: the present study was aimed at characterizing a diamond detector and observing its behavior. materials and methods: the dosimetric characteristics of 6 mv photon beams were measured by utilizing an automatic ptw mp3 scanning system with a diamond detector, and compared with measurements performed with a ptw 31010 ion chamber. results: measurements of dose linearity, dose rate dependence and depth dose distribution as well as dose profiles demonstrated the dosimetric characteristics of the diamond detector. conclusion: some measurements with diamond detector and ion chamber were validated with results published in the literature, demonstrating a good behavior of the diamond detector as compared with the ionization chamber that is widely utilized for dosimetry in radiotherapy, indicating that the diamond detector is a good choice for small field dosimetry.
