Alternatively authors who do not select the gold open access option can choose a ionization chamber measurement. Small field output factors for 6MV FFF beams were measured using the PTW microDiamond detector and the Agility 160–leaf MLC from Elekta. Would the work be better suited to a more clinically- or biologically-focused journal? in the medical physics field over the past few years. Accurate segmentation of organs-at-risk (OARs) is necessary for adaptive head and neck (H&N) cancer treatment planning but manual delineation is tedious, slow, and inconsistent.
