MR-Guided Radiotherapy for Brain and Spine Tumors

Frontiers in Oncology, 2021
MRI is the standard modality to assess anatomy and response to treatment in brain and spine tumors given its superb anatomic soft tissue contrast (e.g., T1 and T2) and numerous additional intrinsic contrast mechanisms that can be used to investigate ...

Systematic review of physical and dosimetric criteria for managing CIEDs in radiotherapy: A medical physicist's perspective. [PDF]

J Appl Clin Med Phys
Abstract Aim Current radiotherapy (RT) guidelines for Cardiac Implantable Electronic Devices (CIEDs) are largely based on clinical management strategies and retrospective reports. This systematic review adopts a medical physics perspective to provide a critical, quantitative analysis of the technical evidence required for developing robust safety ...

Quantification of geometric uncertainties in image guided radiotherapy [PDF]

, 2010
The aim of this thesis is to determine if the geometric uncertainties that are introduced into the image guided radiotherapy (IGRT) process by Cone Beam CT (CBCT) based IGRT equipment are sufficiently small that they do not pose a significant risk of ...

Initial clinical experience with magnetic resonance-guided radiotherapy in pediatric patients: Lessons learned from a single institution with proton therapy

Frontiers in Oncology, 2023
Purpose/ObjectivesMagnetic resonance-guided radiotherapy (MRgRT) is increasingly used in a variety of adult cancers. To date, published experience regarding the use of MRgRT in pediatric patients is limited to two case reports.

Case Report: MR-LINAC-guided adaptive radiotherapy for gastric cancer

Frontiers in Oncology, 2023
BackgroundThe stomach is one of the most deformable organs. Its shape can be easily affected by breathing movements, and daily diet, and it also varies when the body position is different.

MR-guided adaptive versus ITV-based stereotactic body radiotherapy for hepatic metastases (MAESTRO): a randomized controlled phase II trial

Radiation Oncology, 2022
Background Stereotactic body radiotherapy (SBRT) is an established local treatment method for patients with hepatic oligometastasis or oligoprogression. Liver metastases often occur in close proximity to radiosensitive organs at risk (OARs).

Accuracy of deformable image registration-based intra-fraction motion management in Magnetic Resonance-guided radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and Purpose: Intra-fraction motion management is key in Stereotactic Ablative Radiotherapy (SABR) gated delivery. This study assessed the accuracy of automatic tumor segmentation in the delivery of MR-guided radiotherapy (MRgRT) by comparing ...
