Volumetric-modulated arc therapy (VMAT) plan optimization remains a challenging problem due to its non-convex character and the large dimensionality of the solution space. Commonly, the problem is split in three steps: 1) ideal fluence optimization 2) arc seq...

Computed tomography ventilation imaging (CTVI) allows generating ventilation maps from CT data. CTVI provides spatially resolved information on regional lung function that can support functional avoidance and adaptive treatment strategies, but its current rel...
