Joint radial trajectory correction for accelerated T2 * mapping on an MR-Linac.
(WILEY, 2023-05-27)
BACKGROUND: T2 * mapping can characterize tumor hypoxia, which may be associated with resistance to therapy. Acquiring T2 * maps during MR-guided radiotherapy could inform treatment adaptation by, for example, escalating ...
Recommendations for improved reproducibility of ADC derivation on behalf of the Elekta MRI-linac consortium image analysis working group.
(ELSEVIER IRELAND LTD, 2023-09-01)
BACKGROUND AND PURPOSE: The apparent diffusion coefficient (ADC), a potential imaging biomarker for radiotherapy response, needs to be reproducible before translation into clinical use. The aim of this study was to evaluate ...
Accelerating 4D image reconstruction for magnetic resonance-guided radiotherapy.
(ELSEVIER, 2023-07-01)
BACKGROUND AND PURPOSE: Physiological motion impacts the dose delivered to tumours and vital organs in external beam radiotherapy and particularly in particle therapy. The excellent soft-tissue demarcation of 4D magnetic ...
