Impact of tumor motion on target delineation and dose calculation accuracy using rapid‐acquisition HyperSight CBCT in online adaptive radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background HyperSight CBCT offers rapid image acquisition and enhanced image quality, supporting its integration into online adaptive radiotherapy (OART). However, its performance under respiratory‐induced tumor motion requires further evaluation.

Control‐point‐specific plan robustness in volumetric modulated arc therapy‐based cranial radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Progress in mitigating plan degradation due to intrafraction patient motion may involve the identification and management of specific control points that are sensitive to motion. Robust planning in this manner could improve deliverable dosimetry and support advancements toward reducing planning target volume (PTV) margins.

Clinical experience with a same‐day simulation and treatment program for stereotactic radiation therapy on a C‐arm linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose We report our experience with the implementation of a same‐day simulation and treatment C‐arm linear accelerator (linac)‐based stereotactic program for patients with intracranial and extracranial metastatic disease. Methods Between May 2021 and October 2023, patients were treated in our same‐day program with linac‐based SRS/SBRT.

Patient and staff perspective toward marker‐less patient setup accuracy in breast radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose This study comprised two cohorts. The first assessed patient and radiation therapist (RTT) perspectives on temporary ink skin markings. The second evaluated whether integrating a six‐degree‐of‐freedom (6D) couch could further improve setup accuracy, setup time, IGRT time, and total treatment time when used with marker‐less or marker ...

Margin reduction and optimal prescription isodose model for liver stereotactic radiotherapy with respiratory motion

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose This study aimed to establish a framework for optimizing planning target volume (PTV) margins in liver SBRT using virtual 4DCT (v4DCT), by introducing the concept of the Dosimetric Coverage Amplitude (DCA) to quantify motion tolerance and deriving an Optimal Margin (OM) that balances tumor coverage with normal‐tissue sparing.
