Fig. 1 DAO-based pathfinding process. Red color represents negative gradients of the objective function, blue represents positive gradients of the objective function.

Results:

The DAO-based pathfinding for the analyzed case resulted in 6 photon arcs and 1 electron arc. The mean arc span is 100° [60°-260°] with table angles spreading between -70° and 70°. Electron contribution to the mean planning target volume dose is 34.5%. Target coverage and conformity is superior for colli-DYMBER compared to VMAT.
