Five‐year evaluation of linear accelerator‐based SRS platform isocentricity

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS) has become a mainstay in the management of intracranial tumors. However, the high fractional doses and sharp gradients used in SRS place heavy demands on geometric accuracy.

Verification of daily dose recalculation accuracy for an adaptive radiation therapy monitoring tool in helical tomotherapy for nasopharyngeal carcinoma

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose PreciseART, an adaptive radiation therapy (ART) software for helical tomotherapy (HT), was integrated into the Precision treatment planning system (Accuray, Inc., Sunnyvale, CA). It supports automatic monitoring of dose variations to both the target and organs at risk (OARs) throughout the treatment course.

Online correction of intrafraction motion during volumetric modulated arc therapy for prostate radiotherapy using fiducial‐based kV imaging: A cohort study quantifying the frequency of shifts and analysis of men at highest risk

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Various methods exist to correct for intrafraction motion (IFM) of the prostate during radiotherapy. We sought to characterize setup corrections in our practice informed by the TrueBeam Advanced imaging package, and analyze factors associated with IFM.
