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: Deformable image registration (DIR) is increasingly used in the field of
radiation therapy (RT) to account for anatomical deformations. The aims of this paper are to …

High precision conformal radiotherapy requires sophisticated imaging techniques to aid in
target localisation for planning and treatment, particularly when organ motion due to …

Over the last few decades, deformable image registration (DIR) has gained popularity in
image‐guided radiation therapy for a number of applications, such as contour propagation …

Purpose We implemented magnetic resonance–guided breath-hold stereotactic body
radiation therapy in combination with visual feedback using the MRIdian system. Both …

Background and purpose Single-fraction stereotactic ablative radiotherapy (SABR) is an
effective treatment for early-stage lung cancer, but concerns remain about the accurate …

Stereotactic body radiotherapy (SBRT) is rapidly becoming an alternative to surgery for the
treatment of early-stage non-small cell lung cancer patients. Lung SBRT is administered in a …

Purpose To use magnetic resonance image guided radiation therapy (MR-IGRT) for
accelerated partial-breast irradiation (APBI) to (1) determine intrafractional motion of the …

Purpose To study interfractional organ changes during magnetic resonance (MR)-guided
stereotactic ablative radiation therapy for adrenal metastases and to evaluate the dosimetric …

Objective: To evaluate variations in intra-and interfractional tumour motion, and the effect on
internal target volume (ITV) contour accuracy, using deformable image registration of real …
