A description of the first commercially available magnetic resonance imaging (MRI)–guided
radiation therapy (RT) system is provided. The system consists of a split 0.35-T MR scanner …

Purpose: The objective of this work was to develop a quality control (QC) tool to reduce
intensity modulated radiotherapy (IMRT) planning variability and improve treatment plan quality …

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 …

Purpose Magnetic resonance image guided radiation therapy (MR-IGRT) has been used at
our institution since 2014. We report on more than 2 years of clinical experience in treating …

PET with 18 F-FDG has been used in radiation treatment planning for non–small cell lung
cancer (NSCLC). Thresholds of 15%–50% the maximum standardized uptake value (SUV max …

The commissioning of a three‐dimensional treatment planning system requires comparisons
of measured and calculated dose distributions. Techniques have been developed to …

PURPOSE: Locoregional failure remains a significant problem for patients receiving definitive
radiation therapy alone or combined with chemotherapy for non–small-cell lung cancer (…

Image registration and fusion algorithms exist in almost every software system that creates or
uses images in radiotherapy. Most treatment planning systems support some form of image …

Breathing motion is a significant source of error in radiotherapy treatment planning for the
thorax and upper abdomen. Accounting for breathing motion has a profound effect on the size …

Background Recent advances have enabled noninvasive mapping of cardiac arrhythmias
with electrocardiographic imaging and noninvasive delivery of precise ablative radiation with …
