You know what’s an efficient use of linac time? Using a flattening filter free (FFF) setting. This practical dosimetric analysis of lung SBRT demonstrates across 100 cases a median decrease in beam-on time 31-34% for static fields and of 44-52% for dynamic conformal arcs. What’s more, target coverage was not compromised and dose to several nearby organs at risk were reduced. | Savanović, Cancer Invest 2022
