On the role of magnesium in a LiF:Mg,Ti thermoluminescent dosimeter [PDF]
Journal of Physics: Condensed Matter, 2018 LiF doped with Mg and Ti is the most widely used thermoluminescent (TL) dosimeter for a large variety of applications. It has been argued that the Mg dopant is the most important defect in the TL process.

Comparison of organ and effective dose estimations from different Monte Carlo simulation-based software methods in infant CT and comparison with direct phantom measurements. [PDF]
J Appl Clin Med Phys, 2022 Abstract Purpose Computational dosimetry software is routinely used to evaluate the organ and effective doses from computed tomography (CT) examinations. Studies have shown a significant variation in dose estimates between software in adult cohorts, and few studies have evaluated software for pediatric dose estimates.

Accuracy Evaluation of Collapsed Cone Convolution Superposition Algorithms for the Nasopharynx Interface in the Early Stage of Nasopharyngeal Carcinoma. [PDF]
Biomed Res Int, 2022 This study combined the use of radiation dosimeteric measurements and a custom‐made anthropomorphic phantom in order to evaluate the accuracy of therapeutic dose calculations at the nasopharyngeal air‐tissue interface. The doses at the nasopharyngeal air‐tissue interface obtained utilizing the Pinnacle and TomoTherapy TPS, which are based on collapsed ...

A systematic review of electron FLASH dosimetry and beam control mechanisms utilized with modified non-clinical LINACs. [PDF]
J Appl Clin Med PhysAbstract Background FLASH has been shown to spare normal tissue toxicity while maintaining tumor control. However, existing irradiation platforms and dosimetry are not compatible. Consequently, an abundance of FLASH delivery devices and new dosimetry across all modalities has been created.

3D printing of realistic body phantoms: Comparison of measured and simulated organ doses on the example of a CT scan on a pregnant woman. [PDF]
Med PhysAbstract Background Medical examinations or treatment of pregnant women using ionizing radiation are sometimes unavoidable. In such cases, the risk of harm to the embryo and fetus after exposure to ionizing radiation must be carefully estimated. However, no commercially available anthropomorphic body phantoms of pregnant women are available for dose ...

Radiation field and dose inhomogeneities using an X‐ray cabinet in radiation biology research
Medical Physics, Volume 48, Issue 12, Page 8140-8151, December 2021., 2021 Abstract Purpose X‐ray cabinets are replacing 137Cs/60Co sources in radiation biology research due to advantages in size, handling, and radiation protection. However, because of their different physical properties, X‐ray cabinets are more susceptible to experimental influences than conventional sources.

Dosimetry on first clinical dark‐field chest radiography
Medical Physics, Volume 48, Issue 10, Page 6152-6159, October 2021., 2021 Abstract Purpose The purpose of this study was to evaluate the dose characteristic for patient examinations at the first clinical X‐ray dark‐field chest radiography system and to determine whether the effective patient dose is within a clinically acceptable dose range.
