Iterative reconstruction as a novel method of radiation dose reduction at computed tomography in patients with Crohn's disease
… group, that quantified the alarming levels of radiation dose to patients with Crohn’s disease from medical imaging and the notable shift towards CT imaging making these patients an at risk group, provided context for this work. CT delivers some of the highest doses of ionising radiation in …

Optimization of image quality and radiation dose in neuroradiological computed tomography
… of diagnostic quality using the lowest possible radiation exposure. Degradation of image quality, with increased image noise and reduced spatial resolution, is a major limitation for radiation dose reduction in CT. This can be counteracted with new post-processing image filters and iterative …

A Scheme for Ultra-Fast Computed Tomography Based on Stationary Multi-Beam X-ray Sources
… is mainly limited by motion blurring and radiation dose. The conceptual multi-source interior CT scheme has provided a potential solution to reduce motion artifacts and radiation exposure. This dissertation work conducted multi-facet investigations on a novel multi-source interior CT …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
… use of CT results in rapid increase of the CT radiation dose in blunt chest trauma evaluation. Therefore, according to the ALARA (as low as reasonable achievable) principle, radiation dose adjustment in the patients with blunt chest trauma is inevitable. We aimed to evaluate the diagnostic …
