  • Radiotherapy treatment planning
    Patent number: 12478802
    Abstract: Disclosed herein is a method of calculating delivery values for delivering an arc-segment between two control points of a treatment plan, the treatment plan specifying MLC leaf position at each control point. The method comprises: calculating the arc-segment delivery time for each of a plurality of components using default delivery values, wherein one of the components is MLC leaf movement; selecting the component dictating the longest arc-segment delivery time as the time-limiting component; and if the time-limiting component is MLC leaf movement: providing optimised MLC delivery values; if a predetermined condition is met, setting the time-limiting component delivery values to the optimised delivery values; and outputting the time-limiting component delivery values.
