The anatomy of cancer patients changes between radiation treatment planning and delivery
as well as over the course of radiotherapy. Adaptive radiotherapy (ART) aims to deliver …

Radiation therapy treatments are typically planned based on a single image set, assuming
that the patient's anatomy and its position relative to the delivery system remains constant …

Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while
maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is …

Background and purpose Magnetic resonance-guided radiation therapy (MRgRT) has
recently become available in clinical practice and is expected to expand significantly in …

Purpose Technical developments in the field of external beam radiation therapy (RT)
enabled the clinical introduction of image guided intensity modulated radiation therapy (IG …

The ratio of patients who need a treatment adaptation due to anatomical variations at least
once during the treatment course is significantly higher in light ion beam therapy (LIBT) than …

Applicability and accuracy of the rapidly developing tools and workflows for image-guided
radiotherapy need to be validated under realistic treatment-like conditions. We present the …

Background The aim of this study was to evaluate and compare the performance of intensity
modulated radiation therapy (IMRT) plans, planned for low-field strength magnetic …

Introdution: Variation in shape, position and treatment response of both tumor and organs at
risk are major challenges for accurate dose delivery in radiotherapy. Adaptive radiotherapy …

Purpose To review real-time 3-dimensional (3D) image guided radiation therapy (IGRT) on
standard-equipped cancer radiation therapy systems, focusing on clinically implemented …
