Double‐bowtie filter design for pediatric spectral CT imaging: A fan beam simulation study

Medical Physics, Volume 53, Issue 11, November 2026.
Abstract Background Despite concerns about radiation dose in pediatric patients, computed tomography (CT) remains a first‐line imaging modality for children. Spectral CT provides additional diagnostic information that benefits pediatric imaging. However, most existing spectral CT systems are primarily optimized for adult patients.

Comparisons of Water-Equivalent Diameter Measured on Images of Abdominal Routine Computed Tomography with and without A Contrast Agent

Atom Indonesia, 2021
The size-specific dose estimate (SSDE) is a metric for an estimation of patient dose in computed tomography (CT). The SSDE strongly depends on the water-equivalent diameter (DW).

The involvement of aquaporin 5 in the inflammatory response of primary Sjogren’s syndrome dry eye: potential therapeutic targets exploration

Frontiers in Medicine
Sjogren’s syndrome (SS) is a chronic autoimmune disease. Mainly due to the infiltration of lymphoplasmic cells into the exocrine glands, especially the salivary glands and lacrimal glands, resulting in reduced tear and saliva secretion. Reduced tear flow

Host and Environment Shape the Giant Clam‐Associated Photosymbiont Community

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study explored the diversity and composition of Symbiodiniaceae in eight giant clam species across selected sites in the Philippines to gain insights into the factors driving symbiont community structure. Using ITS2 metabarcoding, we discovered that most giant clams were dominated by a single photosymbiont genus, with Cladocopium as the most ...

A study to determine whether the volume-weighted computed tomography dose index gives reasonable estimates of organ doses for thai patients undergoing abdomen and pelvis computed tomography examinations

Journal of Medical Physics, 2017
Introduction: Values for the CTDIvol, which is displayed on scanner consoles, give doses relative to a phantom much larger than most Thai patients, and the CTDIvoldoes not take account of differences in patient size, which affect organ doses.

Assessing Potential Safety Zone Suitability Using a New Online Mapping Tool

Fire, 2022
Safety zones (SZs) are critical tools that can be used by wildland firefighters to avoid injury or fatality when engaging a fire. Effective SZs provide safe separation distance (SSD) from surrounding flames, ensuring that a fire’s heat cannot cause burn ...

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, Volume 73, Issue 9, September 2026.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Effect of arm position, presence of medical devices, and off-centering during acquisition of scout image on automatic tube voltage selection and current modulation in pediatric chest CT. [PDF]

PLoS ONE, 2018
To evaluate the patients' morphologic factors affecting radiation dose in pediatric chest CT.From November 2013 to May 2015, 315 pediatric chest CT scans were obtained using a CT scanner, and classified into 5 groups according to the patients' age.
