Abstract
Methods for training and using a neural network for calculating a 3D dose distribution in water from measured beam profiles for use in radiotherapy are provided. A detector system (300) having a profile detector (302) and a computing system (304) configured to perform the methods is also provided.
Claims21
A method for training (200) a neural network for calculating a 3D dose distribution in water, the method comprising:
- determining at least one beam profile;
- calculating a 3D dose distribution in water based on the determined at least one beam profile;
- and
- training the neural network for calculating the 3D dose distribution in water using the determined at least one beam profile and the calculated 3D dose distribution in water.

A method for calculating (100) a 3D dose distribution in water, the method comprising:
- defining a set of irradiation parameters;
- recording at least one beam profile using a profile detector (302);
- performing a calibration of the profile detector (302) in order to provide the dose in water in Gy, or alternatively using at least one calibrated radiation detector to provide the dose in water in Gy;
- calculating the dose profile of the beam in water using the dose calibration of the profile detector (302);
- and
- calculating the 3D dose distribution in water for one or more of the irradiation parameters of the set of irradiation parameters based on the recorded at least one calibrated beam profile.
