Abstract

In a computerized workflow method for stent planning and conducting a stenting procedure, characteristics of a lesion to be stented are determined from a 3D planning image of the region and selection of an actual stent for stenting the lesion is made with computer-assisted analysis of the lesion based on the characteristics. A virtual stent is electronically generated based on the actual stent, and, using the virtual stent, a best position for the actual stent, for effectively stenting the lesion, is determined. A real time 2D image of the lesion-containing region is displayed during the stenting procedure, with the virtual stent included therein at the aforementioned best position. A physician manually guides the actual stent relative to the lesion during the stenting procedure until the position of the actual stent, as seen in the displayed real time 2D image, coincides with the virtual stent in that image.
