Knowledge‐based deep residual U‐Net (DRU) for synthetic CT generation using a single MR volume for frameless radiosurgery

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose To develop a knowledge‐based deep model for sCT generation from a single MR volume in LINAC‐based frameless SRS, enabling the MR‐only workflow without extra CT simulation. Methods A total of 139 patients were included in the study, with 120 used for training and 19 for testing.

A deep‐learning framework for the prediction of the type of adaptive strategy of MR‐guided prostate radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background and purpose In MR‐guided adaptive radiotherapy (MRgART), adaptive strategies are currently mainly determined through subjective review of anatomical changes. Machine learning (ML) models based on deformable image registration (DIR) have been developed to predict type of adaptive strategy: adapt to position (ATP) versus adapt to ...

Initial follow‐up of mechanical QC tests for RapidArc Dynamic (RAD)

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background RapidArc Dynamic (RAD) is a new solution for delivery of radiotherapy introduced by Varian. RAD blends Volumetric Modulated Arc Therapy (VMAT) and Intensity‐Modulated Radiation Therapy (IMRT) by pausing gantry rotation at predefined positions and adds a degree of freedom: a dynamic collimator.

Online Adaptive MR-Guided Ultrahypofractionated Radiotherapy of Prostate Cancer on a 1.5 T MR-Linac: Clinical Experience and Prospective Evaluation

Current Oncology
The use of hypofractionated radiotherapy in prostate cancer has been increasingly evaluated, whereas accumulated evidence demonstrates comparable oncologic outcomes and toxicity rates compared to normofractionated radiotherapy. In this prospective study,

3D printed collimators and dosimetry for spatially fractionated radiation therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Spatially fractionated radiation therapy (SFRT) has shown incredible potential in sparing normal tissues and activating mechanisms of tumor control distinct from conventional radiotherapy. However, the optimal spatial configuration of SFRT as well as the optimal peak and valley dose values have not been established.

MR-Linac Dosimetry: Current Approaches and Challenges

Journal of Physics: Conference Series, 2023
Abstract The use of MR-integrated linacs (MR-linac) in clinical radiation oncology applications are becoming more prevalent. However, given the novel and radically different designs of these systems from conventional linacs, current radiation dosimetry protocols for high energy photons are no longer appropriate for use in modern MR-linac
