Leaf-individual calibration for a double stack multileaf collimator in photon radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and Purpose: In online adaptive stereotactic body radiotherapy treatments, linear accelerator delivery accuracy is essential. Recently introduced double stack multileaf collimators (MLCs) have new facets in their calibration.

MR-CBCT image-guided system for radiotherapy of orthotopic rat prostate tumors. [PDF]

PLoS ONE, 2018
Multi-modality image-guided radiotherapy is the standard of care in contemporary cancer management; however, it is not common in preclinical settings due to both hardware and software limitations.

Feasibility of tumour-focused adaptive radiotherapy for bladder cancer on the MR-linac

Clinical and Translational Radiation Oncology, 2022
Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. Intra-fraction bladder filling did not

MRI-only based radiotherapy treatment planning for the rat brain on a Small Animal Radiation Research Platform (SARRP) [PDF]

, 2015
Computed tomography (CT) is the standard imaging modality in radiation therapy treatment planning (RTP). However, magnetic resonance (MR) imaging provides superior soft tissue contrast, increasing the precision of target volume selection.

The future of image-guided radiotherapy will be MR guided [PDF]

The British Journal of Radiology, 2017
Advances in image-guided radiotherapy (RT) have allowed for dose escalation and more precise radiation treatment delivery. Each decade brings new imaging technologies to help improve RT patient setup. Currently, the most frequently used method of three-dimensional pre-treatment image verification is performed with cone beam CT.

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 ...

Feasibility of magnetic resonance guided radiotherapy for the treatment of bladder cancer

Clinical and Translational Radiation Oncology, 2020
Whole bladder magnetic resonance image-guided radiotherapy using the 1.5 Telsa MR-linac is feasible. Full online adaptive planning workflow based on the anatomy seen at each fraction was performed. This was delivered within 45 min. Intra-fraction bladder
