Artificial neural network based radiotherapy safety system

A radiation dose monitoring system for monitoring an amount of radiation in a radiation beam generated by a radiation source for a radiation treatment session, wherein the system comprises:

• a radiation sensor that is positioned in a path of the radiation beam and is configured to provide an actual radiation measurement of an amount of radiation in the radiation beam;
• an interface unit, operatively coupled to the at least one radiation sensor;
• a memory unit;
• and
• a processor, operatively coupled to the interface unit and the memory unit, the processor being configured to:
• obtain radiation treatment plan data for the radiation treatment session;
• extract a plurality of feature values for features of radiation field segments from the radiation treatment plan data for the radiation treatment session;
• generate a predicted radiation measurement using an artificial neural network engine that receives the plurality of feature values as inputs;
• and
• determine an error measurement between the actual radiation measurement and the predicted radiation measurement.
