A tandem reinforcement learning framework for localized prostate cancer treatment planning and machine parameter optimization

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Volumetric modulated arc therapy (VMAT) machine parameter optimization (MPO) is a complex, high‐dimensional problem typically solved with inverse planning solutions that are both temporally and computationally expensive. While machine learning techniques have been explored to automate this process, they often supplement rather than ...

Impact of intrafraction changes in delivered dose of the day for prostate cancer patients treated with stereotactic body radiotherapy via MR-Linac

open access: yesTechnical Innovations & Patient Support in Radiation Oncology, 2022
Purpose: The purpose of this study is to evaluate the impact of intrafraction pelvic motion by comparing the adapted plan dose (APD) and the computed delivered dose of the day (DDOTD) for patients with prostate cancer (PCa) treated with SBRT on the MR ...

Surrogate-driven respiratory motion models for MRI-guided lung radiotherapy treatments [PDF]

open access: yes, 2022
An MR-Linac integrates an MR scanner with a radiotherapy delivery system, providing non-ionizing real-time imaging of the internal anatomy before, during and after radiotherapy treatments.

Dosimetric characterization of a novel commercial plastic scintillation detector with an MR‐Linac

open access: yesMedical Physics (Lancaster), 2023
Plastic scintillators have been used as radiation detectors for the past few years, as they are water‐equivalent and independent of the dose, dose rate, and angle of incidence.

Characterization of a deformable beating cardiac phantom with real‐time dosimetric capabilities for validation of MRI‐guided heart radiotherapy

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Stereotactic arrhythmia radioablation (STAR) has emerged as a salvage treatment for patients with ventricular tachycardia, and the MR‐linacs offer MRI‐guidance during such treatment. However, available workflows on MR‐linacs are not yet optimized and characterized dedicatedly to perform heart radiotherapy due to a lack of realistic ...

PSMA PET‐directed radiotherapy for prostate cancer: From precision planning to future innovations

open access: yesVIEW, Volume 7, Issue 1, February 2026.
Prostate‐specific membrane antigen (PSMA) positron emission tomography (PET) imaging enables highly sensitive detection of prostate cancer recurrence and precise lesion mapping. This review summarizes current evidence and emerging applications of PSMA PET in radiotherapy, including diagnostic staging, target delineation, adaptive planning, and outcome ...

Measurement validation of treatment planning for a MR‐Linac [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2019
AbstractPurposeThe magnetic field can cause a nonnegligible dosimetric effect in an MR‐Linac system. This effect should be accurately accounted for by the beam models in treatment planning systems (TPS). The purpose of the study was to verify the beam model and the entire treatment planning and delivery process for a 1.5 T MR‐Linac based on ...
