Purpose: To report the early clinical outcomes of combining intensity-modulated radiation therapy (IMRT) and proton (IMPT) in comparison with IMRT alone treating oropharynx cancer (OPC) patients. Materials Methods: The medical records 148 OPC patients who underwent definitive radiotherapy (RT) concurrent systemic therapy, from January 2016 till December 2019 at Samsung Medical Center, were retr...

Introduction: Electronic portal imaging devices (EPIDs) are extensively used for dosimetric information of pre-treatment field verification and in-vivo dosimetry for Intensity Modulated Radiotherapy (IMRT). In the present work, we have implemented the newly developed portal dosimetry software using independent dose prediction algorithm EPIDose and evaluated this new tool for the pretreatment IM...

60-year-old woman was treated for a brain metastasis. the patient received intensity-modulated radiation therapy (sib-imrt) dose of 30 gy for the whole brain and 40 gy delivered simultaneously to individual brain metastases in 10 fractions. the present report investigated the influence of applied novel prepared treatment plan, among others the fractionation protocol on the electroencephalogram ...

Purpose : This study aims to compare the dosimetric differences in intensity-modulated proton therapy (IMPT) using pencil beam scanning technology and photon-based radiotherapy (IMRT) hypofractionated whole-breast irradiation (HF-WBI) find out more beneficial technique. Methods Materials Eight breast cancer (BC) patients with pathological stage T1 ~ 2N0M0 were immobilized underwent 4D-CT used d...
