Abstract Computational fluid dynamics (CFD) simulations are increasingly utilised to evaluate intracranial aneurysm (IA) haemodynamics aid in the prediction of morphological changes and rupture risk. However, these models vary differences published results warrant investigation IA-CFD reproducibility. This study aims explore sources intra-team variability determine its impact on morphology CFD parameters. A team four operators were given six sets magnetic resonance angiography data spanning...
Digital Image Correlation (DIC) has been widely used as a non-contact deformation measurement technique. Nevertheless, its accuracy is greatly affected by the speckle pattern on specimen. To systematically evaluate how deformability affects precision of DIC algorithms. In this study, test dataset 2D patterns with various prescribed fields was numerically generated, containing two categories speckles, i.e., deformable and non-deformable (rigid) ones. This to performance inverse compositional...
Intracranial aneurysms are relatively common life-threatening diseases, and assessing aneurysm rupture risk identifying the associated factors is essential. Parameters such as Oscillatory Shear Index, Pressure Loss Coefficient, Wall Stress reliable indicators of intracranial development risk, but surface irregular pulsation has also received attention in assessment.
Recent studies have suggested that irregular pulsation of intracranial aneurysm during the cardiac cycle may be potentially associated with rupture risk. However, there is a lack quantification method for pulsations. This study aims to quantify pulsations by displacement and strain distribution surface using four-dimensional CT angiographic image data. Four-dimensional angiography was performed in 8 patients. The data divided into approximately 20 phases, were detected four aneurysms visual...
