Quantitative evaluation of the effect of anatomical changes on the results of in vivo dosimetry during radiation therapy in the thoracic region. [PDF]

J Appl Clin Med Phys
Abstract Background Anatomical changes during thoracic radiation therapy can alter dose delivery and compromise accuracy. Electronic portal imaging device (EPID)‐based in vivo dosimetry (IVD) enables noninvasive monitoring of these changes during treatment. Purpose This study quantitatively evaluated the impact of EPID‐based IVD in volumetric modulated
