Spatial Distribution of Noise Reduction in Four Iterative Reconstruction Algorithms in CT—A Technical Evaluation

Diagnostics, 2020
Iterative reconstruction (IR) is a computed tomgraphy (CT) reconstruction algorithm aiming at improving image quality by reducing noise in the image. During this process, IR also changes the noise properties in the images.

Automatic Synthesis of Anthropomorphic Pulmonary CT Phantoms. [PDF]

, 2016
The great density and structural complexity of pulmonary vessels and airways impose limitations on the generation of accurate reference standards, which are critical in training and in the validation of image processing methods for features such as ...

Beyond the Classroom: Cognitive and Educational Insights Into Gameplay‐Based Second Language Learning

Future in Educational Research, EarlyView.
ABSTRACT This pilot study investigated how the narrative‐rich Chinese AAA game Black Myth: Wukong supports advanced Mandarin learners. Using reflective journals, semi‐structured interviews, and exploratory electroencephalogram (EEG), we examined learners' cognitive, affective, and cultural experiences.

Anthropomorphic Multi-tissue Head Phantom for Microwave Imaging Devices Testing

2023 17th European Conference on Antennas and Propagation (EuCAP), 2023
This paper describes the realization of a versatile anthropomorphic multi-tissue head phantom for testing microwave imaging devices, employing mixtures featuring readily available, not harmful, and stable components. Considering that the evaluation of devices, such as medical ones, might require the variation of the characteristics of the tissues for ...

Form and Law ‐ Rupert Riedl's Significance for Morphology

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Rupert Riedl showed in his “Order in Living Organisms” that morphology can produce law statements and is, therefore, a proper, that is, nomothetic, science. Furthermore, he coined useful terms (interphene and metaphene) and concepts (burden, cadre and minimal homology).

Paediatric computed tomography diagnostic reference levels in Africa: A systematic review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 139-147, March 2025.
Improvements in computed tomography (CT) technology have increased its applications in medical imaging. Variations in the paediatric DRLs indicate that harmonisation and standardisation of paediatric CT protocols are essential for the optimisation of paediatric doses. Abstract Introduction Improvements in computed tomography (CT) technology in terms of

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.
In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

Does AI at Work Increase Stress? Text Mining Social Media About Human–AI Team Processes and AI Control

Journal of Organizational Behavior, EarlyView.
ABSTRACT With rising use of artificial intelligence (AI) in organizations, alongside increasing mental health issues, we seek to understand how AI use affects human stress. Drawing on the automation–augmentation perspective, we propose that AI control over decision‐making thwarts human autonomy and thus contributes to stress.
