Findings on Biomedicine and Biomedical Engineering Reported by Investigators at University of Sheffield (Uncertainty assessment of imaging techniques for the 3D reconstruction of stent geometry)

By a News Reporter-Staff News Editor at Biotech Week -- Fresh data on Biotechnology are presented in a new report. According to news reporting originating from Sheffield, United Kingdom, by NewsRx correspondents, research stated, "This paper presents a quantitative assessment of uncertainty for the 3D reconstruction of stents. This study investigates a CP stent (Numed, USA) used in congenital heart disease applications with a focus on the variance in measurements of stent geometry."

Our news editors obtained a quote from the research from the University of Sheffield, "The stent was mounted on a model of patient implantation site geometry, reconstructed from magnetic resonance images, and imaged using micro-computed tomography (CT), conventional CT, biplane fluoroscopy and optical stereo-photogrammetry. Image data were post-processed to retrieve the 3D stent geometry. Stent strut length, separation angle and cell asymmetry were derived and repeatability was assessed for each technique along with variation in relation to p,CT data, assumed to represent the gold standard. The results demonstrate the performance of biplanar reconstruction methods is comparable with volumetric CT scans in evaluating 3D stent geometry. Uncertainty on the evaluation of strut length, separation angle and cell asymmetry using biplanar fluoroscopy is of the order +/- 0.2 mm, 3 degrees and 0.03, respectively."

According to the news editors, the research concluded: "These results support the use of biplanar fluoroscopy for in vivo measurement of 3D stent geometry and provide quantitative assessment of uncertainty in the measurement of geometric parameters."
