Assessment of dose distribution in pancreatic SABR in the presence of a metallic biliary stent using Monte Carlo modeling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic ablative radiotherapy (SABR) with dose escalation is increasingly used for pancreatic cancer; however, the dosimetric impact of metallic biliary stents remains poorly characterized. Self‐expanding metal stents (SEMS), commonly placed for obstructive jaundice, contain high‐density nitinol that produces computed ...

A geometry‐based scaling model for stereotactic treatment volume definition in stereotactic centralized ablative radiation therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic Centralized Ablative Radiation Therapy (SCART) is a spatially fractionated radiotherapy strategy designed for large or bulky tumors by delivering an intensified ablative dose to a centrally located subvolume while allowing controlled dose reduction toward the tumor periphery.

Surface‐Guided Radiotherapy for Vulvar Cancer in the Frog‐Leg Position: Setup Accuracy and BMI Effects

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Radiotherapy for vulvar carcinoma often employs the “frog‐leg” position to minimize skin toxicity, but this position is biomechanically unstable and prone to setup errors using conventional skin markings. Purpose To evaluate the clinical efficacy of Surface‐Guided Radiotherapy (SGRT) for setup accuracy in vulvar cancer patients ...

AI‐assisted VMAT planning incorporating deep learning‐based dose prediction for head and neck cancer: feasibility of quality standardization and human intervention for irregular cases

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Volumetric‐modulated arc therapy (VMAT) represents a standard of care for head and neck cancer (HNC). However, treatment plan quality depends heavily on the planner's expertise, thereby challenging the standardization of treatment quality.

VMAT - volumetrična modulirana ločna terapija

Onkologija, 2012
Volumetrična modulirana ločna terapija (angl. Volumetric Modulated Arc Therapy, VMAT) je ena izmed najsodobnejših obsevalnih tehnik, ki jo od marca 2011 uporabljamo tudi v Sektorju radioterapije na Onkološkem inštitutu v Ljubljani. Temeljna značilnost VMAT je, da linearni pospeševalnik seva fotonski snop ves čas kroženja glave obsevalnika okoli ...

Dosimetric and clinical validation of a high‐density bolus for superficial skin tumors treated with radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Accurate dose deposition in superficial radiotherapy remains challenging due to the inherent skin‐sparing effect of megavoltage photon beams and difficulties in ensuring bolus conformity. Purpose This study aims to comprehensively evaluate the dosimetric characteristics of the room‐temperature‐malleable high‐density bolus, to ...

Dosimetric comparison of 3D-conformal radiotherapy, volumetric modulated arc therapy, and h-VMAT in left breast radiotherapy under free-breathing and breath-hold conditions

Scientific Reports
This study investigates the role of the h-VMAT (a hybrid of 3DCRT and VMAT) technique in the Deep Inspirational Breath-Hold (DIBH) method for left-breast irradiation by comparing dosimetric parameters of 3DCRT, VMAT, and h-VMAT plans in free breathing ...

Performance evaluation of a new type of commercial silicon detectors for photon beam dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Modern radiotherapy relies on advanced treatment techniques that utilize a large number of small fields, for which maintaining dosimetric accuracy is often challenging. Most vendors have introduced microdetectors suitable for small field dosimetry. Sun Nuclear has developed two silicon diodes with a sensitive volume of 0.35 mm3 that

Initial experience of clinical implementation of an Online Simulation‐free CBCT‐based Adaptive Radiotherapy (OSCAR) workflow for palliative and urgent treatment indications

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.
