The article presents a study which evaluates small lung tumour doses irradiated by intensity-modulated radiotherapy (IMRT) in order to understand the risk of dose calculation errors in radiation such as stereotactic lung radiotherapy (SLRT). The study used pencil beam convolution (PBC) and anisotropic analytic algorithm (AAA). Results revealed that the peripheral doses of the lung tumours were decreased through decreasing the small sliding window apertures (SWA).
