Medical Physics Adaptive Radiotherapy (MPART) Fellowship: Bridging the Training Gap in Online Adaptive Radiotherapy. [PDF]

Healthcare (Basel)
Online adaptive radiotherapy (ART) is rapidly transforming clinical radiation oncology by enabling adaptation of treatment plans based on patient-specific anatomical and biological changes. However, most medical physics training programs lack structured education in ART.

Intrafraction motion analysis in online adaptive radiotherapy for esophageal cancer

Physics and Imaging in Radiation Oncology, 2023
Intrafraction motion during magnetic resonance (MR)-guided dose delivery of esophageal cancer tumors was retrospectively analyzed. Deformable image registration of cine-MR series resulted in gross tumor volume motion profiles in all directions, which ...

STAT-ART: The Promise and Practice of a Rapid Palliative Single Session of MR-Guided Online Adaptive Radiotherapy (ART)

Frontiers in Oncology, 2019
This work describes a novel application of MR-guided online adaptive radiotherapy (MRgoART) in the management of patients whom urgent palliative care is indicated using statum-adaptive radiotherapy (STAT-ART). The implementation of STAT-ART, as performed

Intra-adaptational changes in online adaptive radiotherapy: from the ideal to the real dose. [PDF]

Strahlenther Onkol
Abstract Background and purpose Online adaptive radiotherapy has demonstrated dosimetric benefits by accounting for interfractional organ variations. However, this study investigates the dosimetric impact of intra-adaptational anatomical changes that take place during the adaptation process.

Bringing online adaptive radiotherapy to a standard C-arm linac

Physics and Imaging in Radiation Oncology
Current online adaptive radiotherapy (oART) workflows require dedicated equipment. Our aim was to develop and implement an oART workflow for a C-arm linac which can be performed using standard clinically available tools.

Adaptive margins for online adaptive radiotherapy [PDF]

Physics in Medicine & Biology, 2022
Abstract Objective. In online adaptive radiotherapy a new plan is generated every fraction based on the organ and clinical target volume (CTV) delineations of that fraction. This allows for a planning target volume margin that does not need to be constant over the whole course of treatment, as ...

Online Adaptive Radiotherapy for an Elderly Patient With Locally Advanced Pancreatic Cancer. [PDF]

Cureus
This case report details the treatment process and outcomes of an elderly patient with locally advanced pancreatic cancer (LAPC) managed with online adaptive radiotherapy (ART) guided by fan-beam computed tomography. The patient exhibited significant tumor regression (partial response) during the treatment course.

Automatic AI-based contouring of prostate MRI for online adaptive radiotherapy

Zeitschrift für Medizinische Physik
Background and purpose: MR-guided radiotherapy (MRgRT) online plan adaptation accounts for tumor volume changes, interfraction motion and thus allows daily sparing of relevant organs at risk.

Clinical experiences with online adaptive radiotherapy of vulvar carcinoma

Acta Oncologica, 2023
Radiotherapy for vulvar carcinoma is challenging due to relatively high risk of locoregional disease recurrence, a technically challenging target, and postoperative lymphocele, and a high risk radiation sequelae. We aim to explore, if it is possible to reduce dose to normal tissue, while maintaining CTV coverage for this patient group with online ...

Practical guidelines of online MR-guided adaptive radiotherapy

Journal of Radiation Research, 2022
Abstract The first magnetic resonance (MR)-guided radiotherapy system in Japan was installed in May 2017. Implementation of online MR-guided adaptive radiotherapy (MRgART) began in February 2018. Online MRgART offers greater treatment accuracy owing to the high soft-tissue contrast in MR-images (MRI), compared to that in X-ray imaging ...
