Multi-institutional experience treating patients with cardiac devices on a 1.5 Tesla magnetic resonance-linear accelerator and workflow development for thoracic treatments

Physics and Imaging in Radiation Oncology
Background and purpose: Patients with cardiac implantable electronic devices (CIED patients) are often ineligible for online magnetic resonance-guided radiotherapy (MRgRT), most likely due to the absence of established guidelines.

Performance of a cylindrical diode array for use in a 1.5 T MR-linac

, 2016
At the UMC Utrecht, a linear accelerator with integrated magnetic resonance imaging (MRI) has been developed, the MR-linac. Patient-specific quality assurance (QA) of treatment plans for MRI-based image guided radiotherapy requires QA equipment ...

Intrafractional Tumour-Tracked Irradiation using a Linac-MR

, 2013
Intrafractional tumour tracking is of considerable interest as a means to minimize the PTV in treating mobile tumours. By utilizing the intrafractional MR imaging feature of linac-MR, this thesis seeks to develop a direct, non-surrogate based ...

Modelling the x-ray source for the Australian MRI-Linac

, 2019
MRI-guided radiotherapy allows real-time imaging during treatment however the magnetic field influences the dose distribution in the patient. An accurate model of the radiation beam and the encompassing magnetic field is important to predict dosimetry ...
