1. A radiotherapy dose analysis system comprising:
a delivery information extractor configured to determine delivered radiotherapy treatment information including dose, time and position information;
a physics dose model engine configured to determine planned radiotherapy treatment information including dose, dose rate, time and position information from a radiotherapy treatment plan; and
a dose/dose rate comparison engine configured to
receive calibration information and reconstruct a dose rate of the delivered radiotherapy treatment information from the calibration information and the dose, time and position information of the delivered radiotherapy treatment information,
reconstruct dose and dose rate information in two or three dimensions to compare the dose rate and the dose, time and position information of the delivered radiotherapy treatment information to the dose, dose rate, time and position information of the planned radiotherapy treatment plan and
generate a graphical representation of one or more of the dose rate and dose, dose rate, time and position information of the delivered radiotherapy treatment information versus the dose, dose rate, time and position information of the planned radiotherapy treatment plan.
