Utilization of spectral filteration for ultra‐low dose brain CT in pediatric patients for diagnosis of craniosynostosis: A phantom study Open
Objectives This study evaluates the effectiveness of spectral filtration—specifically Tin and SilverBeam filters—in achieving ultra‐low radiation doses in pediatric computed tomography (CT) imaging for craniosynostosis diagnosis. We invest…

Development and Initial Evaluation of an In‐House Paediatric <span>CT</span> Immobilisation Device Open
Introduction Paediatric imaging often requires immobilisation to reduce motion artefacts, reduce the risk of repeat imaging and subsequently reduce patient radiation exposure. Commercial immobilisation devices may be expensive and infreque…

<i>RapidAI</i> Compared With Human Readers of Acute Stroke Imaging for Detection of Intracranial Vessel Occlusion Open
Background Rapid detection of intracranial arterial occlusion in patients with ischemic stroke is important to facilitate timely reperfusion therapy. We compared the diagnostic accuracy of neurologists and radiologists against RapidAI (iSc…

Comparison of organ and effective dose estimations from different Monte Carlo simulation‐based software methods in infant CT and comparison with direct phantom measurements Open
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…

Iterative Model Reconstruction in Lumbar Spine Image Retrieval from Computed Tomography of the Abdomen and Pelvis Open
Objective:We sought to compare the image quality of iterative model reconstruction (IMR) with statistical iterative reconstruction (SIR) in lumbar spine (L-spine) images reconstructed from computed tomography (CT) image data from examinati…

Efficacy of fine focal spot technique in CT angiography of neck Open
Objectives: Focal spot size partially defines spatial resolution of a CT system. Many CT tubes have two focal spot sizes, with the finer one allowing more detailed imaging at the cost of photon intensity and increased heat production. Impr…

Orthopaedic and non-orthopaedic applications of a single-energy iterative metal artefact reduction technique and other metal artefact reduction techniques explained Open
Metal within the CT field of view causes artefact that degrades the diagnostic quality of the processed images. This is related to the high atomic number of most metals and is due to a combination of beam hardening, scatter, edge effects a…
