Multi-parametric Improvements in the CCD Camera-based EPID for Portal Dosimetry
Journal of Medical Signals and Sensors, 2017 Dosimetric verification of radiation treatment has recently been extended by the introduction of electronic portal imaging devices (EPIDs). Detailed dose response specifications of EPID should be addressed prior to any dosimetric application. The present

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 PhysAbstract 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

Sensitivity and concordance study of an open source EPID-based linear accelerator test suite. [PDF]
J Appl Clin Med PhysAbstract Background Electronic portal imaging devices (EPIDs) enhance linear accelerator (linac) quality assurance (QA) efficiency but are not universally used beyond patient‐specific IMRT QA. A multi‐institutional Consortium seeks to standardize linac QA utilizing an EPID‐based test suite.

Radiological Loco-Regional Treatments for Cholangiocarcinoma: A Systematic Review of the Literature. [PDF]
Liver IntABSTRACT Cholangiocarcinoma (CCA) is the second most common primary liver cancer and is being diagnosed with increasing frequency worldwide. We performed a systematic review on radiofrequency (RFA), microwave (MWA), irreversible electroporation (IRE), trans‐arterial chemoembolization (TACE) and selective internal radiation therapy (SIRT) in CCA. Thirty‐

Commissioning of a near real-time in vivo film dosimetry system. [PDF]
J Appl Clin Med PhysAbstract Background Accurate in vivo dosimetry is crucial for dose monitoring of cardiac implantable electronic devices (CIED) and for dose verification for special procedures such as total body irradiation (TBI) and total skin electron therapy (TSET). Purpose A new near real‐time in vivo dosimetry system using radiochromic films (RCF) is investigated ...
