Purpose Patient‐specific IMRT QA measurements are important components of processes
designed to identify discrepancies between calculated and delivered radiation doses …

The gamma index (γ) is one of the most commonly used metrics for the verification of
complex modulated radiotherapy. The mathematical definition of the γ is computationally …

Semiconductor dosimeters are ubiquitous in modern external-beam radiation therapy. They
possess key features. The response, electronically available in real time, is stable and linear …

Recent advances in radiotherapy technology and techniques have allowed a highly
conformal radiation to be delivered to the tumour target inside the body for cancer treatment …

Purpose Despite their availability and simplicity of use, Electronic Portal Imaging Devices
(EPID s) have not yet replaced detector arrays for patient specific QA in 3D. The purpose of …

The objective of this paper is to provide a comprehensive review of the advancements and
techniques in real time two-dimensional (2D) dosimetry for external radiation therapy with …

Purpose Aim of this work was to study how the detector resolution can affect the clinical
significance of SBRT pre-treatment volumetric modulated arc therapy (VMAT) verification …

In this project, we investigated the use of an electronic portal imaging device (EPID),
together with the treatment planning system (TPS) and MLC log files, to determine the …

Purpose Robotic radiosurgery demands comprehensive delivery quality assurance (DQA),
but guidelines for commissioning of the DQA method is missing. We investigated the stability …

Aim To evaluate the new Octavius 4D system for patient specific quality assurance and to
study the correlation between plan complexity and gamma index analysis in patient specific …
