Fig. 1 Schematic diagram showing the concept of hybrid IMRT and VMAT optimisation and delivery. (a) The arc is divided into segment groups and fluence is optimised for each group. (b) The segment groups are further optimised for either VMAT delivery (blue) or IMRT delivery (red). VMAT segments are distributed over the gantry range of each segment group, while IMRT segments are all positioned at the central gantry angle of each segment group. The whole sequence is delivered as a single beam.
