Dynamic modulated arc therapy (DMAT): A time‐aware, modulation‐steered optimization framework for next‐generation radiotherapy delivery

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Conventional VMAT optimization largely treats delivery time and deliverability as emergent properties of simplified, control‐point‐centric models that often ignore finite acceleration and other dynamic limits. As modern linacs continue to increase maximum axis speeds and dose rates, there is a growing need for a planning paradigm ...

Definition and quality requirements for stereotactic radiotherapy: consensus statement from the DEGRO/DGMP Working Group Stereotactic Radiotherapy and Radiosurgery [PDF]

, 2020
Stereotactic radiotherapy with its forms of intracranial stereotactic radiosurgery (SRS), intracranial fractionated stereotacticradiotherapy (FSRT) and stereotactic body radiotherapy (SBRT) is today a guideline-recommended treatment for malignant or ...

Evaluation of the environ SRS immobilization mask system for HyperArc: Dosimetric attenuation, dose calculation accuracy, and clinical setup reproducibility

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Frameless thermoplastic masks are standard for intracranial stereotactic radiosurgery (SRS), with the Encompass (CQ Medical) widely used on the Varian HyperArc platform. A candidate mask must minimize beam attenuation, permit accurate dose calculation, and enable reproducible setup, yet these are rarely assessed together ...

Log file‐based patient‐specific quality assurance for MR‐guided radiation therapy with comprehensive motion management

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Patient‐Specific Quality Assurance (PSQA) for Elekta Unity MR‐Linac treatments delivered under Comprehensive Motion Management (CMM) is challenging because beam gating, unexpected interruptions, and split sub‐segments introduce delivery complexities that are not fully addressed by conventional quality assurance workflows.

Towards adaptive radiotherapy: Comparing HyperSight and standard CBCT reconstructions on a C‐Arm Linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is integral to image‐guided radiation therapy and increasingly used for adaptive radiotherapy and CBCT‐based dose calculation. Conventional kV‐CBCT systems on C‐arm TrueBeam linacs with Feldkamp–Davis–Kress (FDK) reconstruction have historically been limited by reduced Hounsfield Unit (HU ...

A radiocirurgia estereotáxica em tumores benignos e malignos do sistema nervoso central.

Acta Médica Portuguesa, 2005
Stereotactic Radiosurgery has proven to be during the last years the therapy of choice in more and more patients with benign and malignant brain tumors. The potential advantages comparatively to surgery and conventional radiotherapy made this technique a

A group‐based hands‐on seminar for teaching failure mode and effects analysis in CyberKnife stereotactic radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Risk analysis is becoming increasingly important in advanced radiotherapy, as treatment workflows grow more complex and require multidisciplinary expertise. Although failure mode and effects analysis (FMEA) has been recommended for risk‐based quality management, opportunities for users to practically learn and apply FMEA within ...
