Quantifying inter-fraction cardiac substructure displacement during radiotherapy via magnetic resonance imaging guidance [PDF]

open access: yes, 2021
Emerging evidence suggests cardiac substructures are highly radiosensitive during radiation therapy for cancer treatment. However, variability in substructure position after tumor localization has not been well characterized.

Planning for Preservation: Feasibility of Erectile Tissue Sparing During Prostate Stereotactic Radiotherapy

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 4, Page 465-472, December 2025.
Cure and quality of life is the modern definition of successful prostate cancer treatment, and preservation of continence and sexual function relates closely to treatment outcome satisfaction. This retrospective planning study aimed to determine if erectile tissue could be spared whilst maintaining clinically acceptable doses to target volumes. Results

Magnetic Resonance-based Response Assessment and Dose Adaptation in Human Papilloma Virus Positive Tumors of the Oropharynx treated with Radiotherapy (MR-ADAPTOR): An R-IDEAL stage 2a-2b/Bayesian phase II trial

open access: yesClinical and Translational Radiation Oncology, 2018
Background: Current standard radiotherapy for oropharynx cancer (OPC) is associated with high rates of severe toxicities, shown to adversely impact patients’ quality of life. Given excellent outcomes of human papilloma virus (HPV)-associated OPC and long-

Reirradiation: Standards, challenges, and patient‐focused strategies across tumor types

open access: yesCA: A Cancer Journal for Clinicians, Volume 75, Issue 6, Page 630-666, November/December 2025.
Abstract Reirradiation (reRT), defined as administering a course of radiation therapy to a specific area previously irradiated, is an evolving treatment strategy for locoregionally recurrent cancer that offers significant potential and poses inherent challenges.

The effect of density overrides on magnetic resonance-guided radiation therapy planning for lung cancer

open access: yesPhysics and Imaging in Radiation Oncology, 2018
Background and Purpose: Inverse treatment planning for lung cancer can be challenging since density heterogeneities may appear inside the planning target volume (PTV).

Measurement of isocenter accuracy and image distortion in magnetic resonance-guided radiotherapy [PDF]

open access: yes, 2020
Magnetic resonance (MR)-guided radiotherapy involves complex irradiation- and imaging devices (MR-Linacs), as well as complex treatment procedures. To assure accurate patient treatments, both have to be tested for proper functioning. Here, new methods to

Efficacy of Treatments for T3bN0M0 Prostate Cancer Patients: A Systematic Review and Meta‐Analysis

open access: yesThe Prostate, Volume 85, Issue 15, Page 1395-1411, November 2025.
ABSTRACT Background Patients with prostate cancer (PC) invading into the seminal vesicles (SV) constitute a specific subgroup of high‐risk patients (staged as T3b) with a particularly high risk of disease recurrence, even when lymph node or distant metastases are absent (N0M0).

MR-guidance in clinical reality: current treatment challenges and future perspectives

open access: yesRadiation Oncology, 2019
Magnetic Resonance-guided radiotherapy (MRgRT) marks the beginning of a new era. MR is a versatile and suitable imaging modality for radiotherapy, as it enables direct visualization of the tumor and the surrounding organs at risk.

Bayesian model selection approach to boundary detection with non-local priors [PDF]

open access: yes, 2018
Based on non-local prior distributions, we propose a Bayesian model selection (BMS) procedure for boundary detection in a sequence of data with multiple systematic mean changes.

A self‐gated 4D‐MRI sequence for internal target volume delineation in liver: Phantom and pre‐clinical validation

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Background The poor soft tissue resolution of four‐dimensional computed tomography (4D‐CT) limits its utility in delineating liver cancer target volumes. Purpose To compare the consistency between four‐dimensional magnetic resonance imaging (4D‐MRI) using T1‐weighted (T1w) radial stack‐of‐stars (SOS) gradient echo (GRE) sequences and 4D‐CT in ...
