MPLA case: A proposal for purchasing SRS/SBRT QA equipment

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract This work of fiction is part of a case study series developed by the medical physics leadership academy (MPLA). It is designed to generate discussion of the managerial and leadership challenges medical physicists can face. Through discussion and quantitative analysis, the case aims to teach learners basic finance concepts and build their ...

Fine wine, art, and medical physicist bibliometrics: Things that improve with age

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Purpose Bibliometric indicators are widely used to evaluate faculty productivity, yet these metrics change with career stage, evolving authorship practices, and technological shifts in how science is produced. This study examines patterns of scholarly output among radiation therapy medical physics faculty at leading cancer centers and provides

Automated decision support tool for static angle modulated ports configuration in VMAT with dynamic collimator rotation for head and neck cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background RapidArc Dynamic (RAD; Varian Medical Systems, Palo Alto, CA) is a novel volumetric modulated arc therapy (VMAT) technique that features dynamic collimator rotation synchronized with gantry rotation. RAD enables the use of static angle‐modulated ports (STAMPs) defined by user selected gantry and collimator angles.

Feasibility of lattice radiation therapy using a noncoplanar vertex arrangement and dynamic conformal arcs

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Current Lattice radiation therapy (LRT) mainly uses inverse IMRT/VMAT optimization, which is time‐consuming and complex; however the high modulation complexity compromises dosimetric accuracy and blurs the peak‑to‑valley dose ratio.

SRS/SBRT commissioning process with a hybrid beam data model in new preconfigured CyberKnife system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background A new preconfigured CyberKnife system was introduced to improve the SRS/SBRT commissioning efficiency. The vendor provides a reference beam data set, termed “beam data model (BDM)”, and recommends its validation and combination with measurement data to develop a hybrid beam data model (h‐BDM).

Clinical evaluation and regression test of a commercial deep‐learning auto‐segmentation model

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Commercial deep‐learning segmentation (DLS) tools are increasingly used in clinical practice. Software updates may alter segmentation performance, highlighting the need for systematic clinical evaluation before implementation. Purpose This study presents our experience in clinically evaluating and regression‐testing a RayStation DLS

Incidence and Site‐Specific Risk Factors of Jaw Osteoradionecrosis for Head and Neck Patients in the IMRT/VMAT Era: Evidence From a Large, Hospital‐Based Cohort

Head &Neck, Volume 48, Issue 10, Page 2883-2892, October 2026.
ABSTRACT Purpose Osteoradionecrosis (ORN) of the jaw remains a serious late complication of head and neck cancer (HNC) radiotherapy. Although intensity‐modulated radiotherapy (IMRT) and volumetric‐modulated arc radiotherapy (VMAT) are expected to reduce ORN risk, large real‐world data in the modern era are limited.
