Determination of the Unintended Error in the Proton Beam Energy for Radiotherapy
https://doi.org/10.1134/S2304487X2103007X
Abstract
The possibility of using the log files of the Proteus Plus medical device (IBA) is investigated in order to identify an unintentional error in the proton energy value, which, in turn, determines the depth of the Bragg peak in the phantom substance/patient tissue. An unintentional change in the energy of the proton beam has been detected by the displacement of its position in space in the transport system. The beam position has been measured by a strip ionization chamber and has been recorded in the log file of the proton therapy machine. The possibility of detecting such an error using log files has been checked by the controlled perturbation of the beam energy. The described technique has shown the possibility of detecting unintentional errors in the proton beam energy using the log files of the medical device for specific test treatment plans and proton energies. In addition, the parameters measured with the strip ionization chamber and used in the calculation of unintentional error showed stability over time.
