Abstract
A radiation treatment device may include a first dosimeter and a second dosimeter. Quantum efficiency of the first dosimeter may be lower than quantum efficiency of the second dosimeter. A method for monitoring beam energy may include receiving a first signal generated by a first dosimeter, receiving a second signal generated by a second dosimeter, receiving a third signal generated by the first dosimeter and receiving a fourth signal generated by the second dosimeter. The first signal and the second signal may be associated with a first radiation beam. The second signal and the fourth signal may be associated with a second radiation beam. The method may also include determining whether there is a difference between the beam energy of the first radiation beam and the second radiation beam based on at least one of the first signal, the second signal, the third signal or the fourth signal.
