Comparison of EPID portal dosimetry verification and RadCalc dose verification for VMAT treatment plans

open access: yesNowotwory
INTRODUCTION: Dosimetry verification is required before starting each treatment. The legal regulations do not clearly define one method of plan verification.

Biomonitoring of deoxynivalenol and deoxynivalenol-3-glucoside in human volunteers : renal excretion profiles [PDF]

open access: yes, 2019
Biomarkers for the determination of the dietary exposure to deoxynivalenol (DON) have been proposed in the past but so far no quantification of their use in humans has been carried out. Following a human intervention study with two mycotoxins, namely DON

A remote EPID-based dosimetric TPS-planned audit of centers for clinical trials: outcomes and analysis of contributing factors

open access: yesRadiation Oncology, 2018
Background A novel remote method for external dosimetric TPS-planned auditing of intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) for clinical trials using electronic portal imaging device (EPID) has been developed. The

The effect and stability of MVCT images on adaptive TomoTherapy. [PDF]

open access: yes, 2010
Use of helical TomoTherapy-based MVCT imaging for adaptive planning is becoming increasingly popular. Treatment planning and dose calculations based on MVCT require an image value to electron density calibration to remain stable over the course of ...

Assessment of LD‐V1 radiochromic film low‐dose performance for mega‐voltage radiotherapy quality assurance

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Highly modulated radiotherapy delivery demands functional multileaf collimator (MLC) quality assurance (QA) with the ability to measure very low doses during short (<1 s) temporal segments of beam delivery. A radiochromic film with adequate sensitivity in the few‐cGy range is therefore needed.

Streamlining Paediatric Palliative Radiotherapy: A Case Study on Reducing Procedural Burden and Avoiding General Anaesthesia Using a Simulation‐Free Radiotherapy (SF‐RT) Protocol

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue S2, Page S117-S123, April 2026.
This paper presents two cases of young children who were treated with simulation‐free radiotherapy. We demonstrate that this workflow is feasible in children requiring palliative radiotherapy with the potential to expedite treatment, reduce procedural burden on the child and their family, and eliminate a general anaesthetic procedure.

Dosimetric characteristics of a new linear accelerator under gated operation. [PDF]

open access: yes, 2006
Respiratory gated radiotherapy may allow reduction of the treatment margins, thus sparing healthy tissue and/or allowing dose escalation to the tumor. However, current commissioning and quality assurance of linear accelerators do not include evaluation ...
