A Method for Online Dose-Guided Adaptive Radiotherapy [PDF]

Cureus, 2014
A process was developed to allow the delivery of online dose-guided adaptive radiotherapy (DART). DART was defined as the method to utilize patient imaging data and treatment planning data, such as dose fluences to assess the validity and quality of the treatment and the dose delivered to the target volume and critical anatomical structures of the ...

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

Online adaptive radiotherapy and dose delivery accuracy: A retrospective analysis

Journal of Applied Clinical Medical Physics, 2023
AbstractPurposeWith online adaptive radiotherapy (ART), patient‐specific quality assurance (PSQA) testing cannot be performed prior to delivery of the adapted treatment plan. Consequently, the dose delivery accuracy of adapted plans (i.e., the ability of the system to interpret and deliver the treatment as planned) are not initially verified.

Adaptive radiotherapy: The Elekta Unity MR-linac concept

Clinical and Translational Radiation Oncology, 2019
Background and purpose: The promise of the MR-linac is that one can visualize all anatomical changes during the course of radiotherapy and hence adapt the treatment plan in order to always have the optimal treatment.
