Dose calibration of EPIDs for segmented IMRT dosimetry [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2014
The purpose of this study was to investigate the dose response of amorphous silicon (a‐Si) electronic portal imaging devices (EPIDs) under different acquisition settings for both open jaw defined fields and segmented intensity‐modulated radiation therapy (IMRT) fields. Four different EPIDs were used.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Supercritical Fluid Chromatography for Expedited Sample Clean‐Up in Isotope Ratio Mass Spectrometry Including Cholesterol as New Endogenous Reference Compound

open access: yesDrug Testing and Analysis, EarlyView.
Supercritical fluid chromatography was employed in the sample preparation for IRMS determinations in sports drug testing for the first time and the developed method was successfully validated. Cholesterol (CHOL) was introduced as a novel endogenous reference compound and population‐based Δ‐values were established as shown here.

Four-Dimensional In Vivo Dosimetry By Dose Reconstruction Using Continuous Epid Images And Phase Sorting Method

open access: yes, 2023
In vivo dosimetry is widely used for patient specific dose evaluation and treatment verification in external beam radiation therapy (EBRT). There is a growing interest in using an electronic portal imaging device (EPID) for in vivo dosimetry, by ...

A method for determining the performance of formulas for calculating the crack width and spacing in reinforced concrete elements

open access: yesStructural Concrete, EarlyView.
Abstract Numerous studies have been conducted to determine the performance of formulas for calculating crack width and spacing in reinforced concrete structures. Generally, these studies pay limited attention to the application areas of those formulas and how to compare different representations of the crack width and spacing.

Early Interaction Between Scripture, Rule of Faith, and Evolving Christian Doctrine and Tradition: A Response to Alister McGrath’s The Nature of Christian Doctrine

open access: yesInternational Journal of Systematic Theology, EarlyView.
Abstract This response to Alister McGrath’s The Nature of Christian Doctrine examines the interplay between Scripture, the Rule of Faith, and evolving Christian doctrine and tradition. Focusing on McGrath’s critique of Lindbeck’s presentation of doctrinal modalities, the article explores how doctrinal formation involves primarily synchronic (canonical),

Automatic single‐isocenter multiple‐target cranial stereotactic treatment plan optimization via planning system scripting

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Single‐isocenter multiple‐target stereotactic radiation treatments delivered on C‐arm linear accelerators are increasingly common due to practical advantages in both accessibility and speed compared to multiple isocenter treatments.

Super-resolution imaging in a multiple layer EPID [PDF]

open access: yesBiomedical Physics & Engineering Express, 2017
Abstract A new portal imager consisting of four vertically stacked conventional electronic portal imaging device layers has been constructed in pursuit of improved detective quantum efficiency. We hypothesize that super-resolution (SR) imaging can also be achieved in such a system by shifting each layer laterally ...
