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.

MR-LINAC-Guided Adaptive Radiotherapy for Gastric MALT: Two Case Reports and a Literature Review

Radiation, 2022
It is still very challenging to use conventional radiation therapy techniques to treat stomach tumors, although image-guided radiotherapy, mainly by kV X-ray imaging techniques, has become routine in the clinic.

Quantification of geometric uncertainties in image guided radiotherapy [PDF]

, 2010
The aim of this thesis is to determine if the geometric uncertainties that are introduced into the image guided radiotherapy (IGRT) process by Cone Beam CT (CBCT) based IGRT equipment are sufficiently small that they do not pose a significant risk of ...

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.

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
