Abstract
A dose calculation method for brachytherapy treatment, is disclosed, in which radiation is provided by one or more radiation sources from at least a first and a second dwell position within a patient. The method comprises performing a first dose calculation for the first dwell position according to a first dose calculation algorithm and a second dose calculation for the second dwell position according to a second dose calculation algorithm, and using the sum of the first dose calculation and the second dose calculations as the total calculated dose. Different dose engines with different properties can be combined to provide time-efficient calculations with satisfactory accuracy.
Claims14
A computer implemented dose calculation method for brachytherapy treatment, in which radiation is provided by one or more radiation sources from at least a first and a second dwell position within a patient, the radiation provided in each dwell position resulting in a dose contribution from that dwell position, the method comprising selecting a first dose calculation algorithm to be used to calculate the dose contribution from the first dwell position and a second dose calculation algorithm to be used to calculate the dose contribution for the second dwell position, the second dose calculation algorithm being different from the first dose calculation algorithm, calculating the dose contribution from the first dwell position according to the first dose calculation algorithm and calculating the dose contribution from the second dwell position according to the second dose calculation algorithm, and calculating a total dose as the sum of the dose contributions from the at least first and second dwell positions.
