Improving VMAT dose calculation accuracy and planning quality via a GPU‐accelerated Fourier transform dose calculation algorithm

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Inverse planning typically utilizes fast, less accurate dose calculation algorithms during the iterative optimization process, thus leading to dose calculation errors (DCEs) and suboptimal plans that often require dose normalization and/or plan re‐optimization.

The effect of multi‐leaf collimator leaf width on VMAT treatment plan quality

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The advent of volumetric modulated arc therapy (VMAT) in radiotherapy has made it one of the most commonly used techniques in clinical practice. VMAT is the delivery of intensity modulated radiation therapy (IMRT) while the gantry is in motion, and existing literature has shown it has decreased treatment delivery times and the ...
