An X‐ray and γ‐ray combination strategy to exploit steep dose gradients for improved prostate cancer radiotherapy: A dosimetric comparison of Taichi Pro and Halcyon

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose This study aimed to evaluate a novel technological platform, Taichi Pro—which integrates a 6 MV flattening filterfree linear accelerator with a 18 source Rotating Gamma System (RGS) to generate steep dose gradients via multisource focused γ‐rays and noncoplanar arcs—for precision radiotherapy in prostate cancer.

Commissioning and validation of the Elekta One GPUMCD algorithm for an Elekta VersaHD linear accelerator

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose The purpose of this work was to commission and validate GPUMCD, a GPU‐accelerated Monte Carlo dose calculation engine for c‐arm Elekta linear accelerators (linac). This algorithm was recently released for clinical implementation in the Elekta One Treatment Planning System (v6.2.3, EOP). Methods A GPUMCD beam model was generated for all

Impact of Monaco sequencing parameters on monitor units, plan quality, and optimization time for Elekta Unity liver SBRT plans

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Magnetic resonance‐guided radiation therapy (MRgRT) using the Elekta Unity MR‐linac offers significant advantages for liver stereotactic body radiation therapy (SBRT). However, the Unity is limited by a low dose rate and the lack of volumetric‐modulated arc therapy (VMAT), resulting in prolonged treatment times.

Influence of respiratory motion management technique on radiation pneumonitis risk with robotic stereotactic body radiation therapy. [PDF]

open access: yes, 2018
Purpose/objectivesFor lung stereotactic body radiation therapy (SBRT), real-time tumor tracking (RTT) allows for less radiation to normal lung compared to the internal target volume (ITV) method of respiratory motion management. To quantify the advantage

Engineered Bacteria‐Vesicle Delivered Lactate Reprogramming Boosts Tumor Radiosensitivity

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
We engineered a bacterial‐vesicular dual‐delivery platform that targets LOx to colorectal tumors, enabling lactate clearance, immune microenvironment remodeling, and microbiota modulation. This microbe–metabolism synergistic strategy effectively sensitizes colorectal cancer to radiotherapy, offering a promising approach to overcome radioresistance ...

Magnetic Resonance Guided Radiation Therapy (MRgRT) Prostate Motion and Margins

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue 1, Page 44-51, March 2026.
This study evaluated intra‐fractional prostate motion during MR‐guided radiotherapy to determine appropriate PTV margins for prostate cancer. Analysis of 18 patients resulted in calculated margins of 3.2 mm (AP), 1.7 mm (LR), and 3.2 mm (SI), supporting the potential for margin reduction with MRgRT. ABSTRACT Introduction Systematic and random errors in
