Computer-assisted quantitative evaluation of coronary stent platforms by different intracoronary imaging methods

IVUS (intravascular ultrasound) and OCT (optical coherent tomography) both modalities are used for indepth analysis in order to provide a detailed description of the anatomy of coronary artery wall and implanted stent positions. Dedicated, semi-automated visualization for both methods was applied. An adaptable quantification algorithm of stent struts detection for OCT and manual quantification of stent struts for IVUS in a series of drug-eluting stented animal coronary arteries were used. The goal of this research was to find significant details and quantitative differences, of implanted coronary stents in both OCT and IVUS intracoronary imaging methods.
