Independent verification of the dose per monitor unit (MU) to deliver the prescribed dose to a
patient has been a mainstay of radiation oncology quality assurance (QA). We discuss the …

Dosimetry of ionising radiation is a well-established and mature branch of physical sciences
with many applications in medicine and biology. In particular radiotherapy relies on …

Purpose To demonstrate the feasibility of online adaptive magnetic resonance (MR) image
guided radiation therapy (MR-IGRT) through reporting of our initial clinical experience and …

The motivation for this study was to reduce physics workload relating to patient‐specific
quality assurance (QA). VMAT plan delivery accuracy was determined from analysis of pre …

Abstract Background and Purpose The clinical introduction of on-table adaptive
radiotherapy with Magnetic Resonance (MR)-guided linear accelerators (Linacs) yields new …

Purpose Multileaf collimator (MLC) delivery discrepancy between planned and actual
(delivered) positions have detrimental effect on the accuracy of dose distributions for both …

An intensity-modulated proton therapy (IMPT) patient-specific quality assurance (PSQA)
program based on measurement alone can be very time consuming due to the highly …

Background The multileaf collimator (MLC) is a critical component to accurate intensity-
modulated radiotherapy (IMRT) delivery. This study examined MLC positional accuracy via …

Purpose Performing measurement-based patient-specific quality assurance (PSQA) is
recognized as a resource-intensive and time inefficient task in the radiation therapy …

Purpose: To describe the validation and implementation of a novel quality assurance (QA)
system for TomoTherapy using a Monte Carlo (MC)‐based secondary dose calculation and …
