QIvus

QIvus has been developed for the objective and reproducible analysis of tomographic images of both lumen and arterial wall of a coronary or vascular segment, in particular the assessment of a stenosis or artherosclerotic plaque. This information supports the possible placement of intervention devices in these vessels. QIvus enables an advanced assessment of vessel, lumen, and stent morphology. It also avoids the very time-consuming conventional manual tracing of boundaries, which suffers from high intra- and inter observer variability. QIvus can be used to control stent placement and to assess in-stent restenosis. QIvus software package enables the automatic calculation and the display of various parameters such as: areas and diameters in individual slices; volumes over the segment of interest (Simpson’s Rule) for the vessel, lumen and stent contours; plaque and in-stent restenosis parameters.
