Volumetric modulated arc therapy (VMAT) is a common radiation treatment technique that delivers radiation to the planning target volume (PTV) while sparing the organs at risk (OAR). One limitation of VMAT on Varian linear accelerators is the limited distance the multileaf collimators (MLCs) can travel across the x-axis of the treatment field. The researchers in this case study sought to evaluate whether a split-field technique offers improved sparing of OAR, particularly dose to the femoral heads
