Abstract:
1. A method for guiding stent deployment during an endovascular procedure, said method comprising the steps of: constructing a 3-dimensional (3D) digital subtraction angiography (DSA) image of a target blood vessel lesion; determining a length, diameter type, and placement location of a planned stent using said 3D DSA image; creating a virtual model of said stent from said length, diameter type, and placement location of said planned stent; overlaying an outline and shape of said planned stent on a 2-dimensional (2D) DSA image of said target lesion; navigating a real stent to said target lesion by manipulating a stent deployment mechanism; acquiring real-time 2D fluoroscopic images of said stent navigation, and projecting an image of said virtual model of said planned stent onto said fluoroscopic images, wherein 2D fluoroscopic images are acquired from a C-arm mounted X-ray apparatus; and deploying said real stent, when said real stent is aligned with said virtual model of said planned stent in said fluoroscopic images.
