Abstract
A system for estimating post-virtual stenting fractional flow reserve (FFR) capable of: receiving geometrical parameters of a blood vessel segment, the geometrical parameters comprising first, second and third geometrical parameters; with a proximal end as a reference point, deriving a reference lumen diameter function and calculating a pre-virtual stenting percent diameter stenosis based on the above geometrical parameters and the distance from position along the segment to the reference point; receiving a virtual stenting location; calculating a geometrical parameter of a virtual lumen of the post virtually-stented segment, deriving a post-virtual stenting geometrical parameter difference function and calculating a percent diameter stenosis based on the third geometrical parameter, the virtual stenting location and the reference lumen diameter function; taking derivative difference functions of the post-virtual stenting geometrical parameter difference function in multiple scales; and obtaining FFR based on the multiple scales of derivative difference functions and a maximum post-virtual stenting mean blood flow velocity. Post-virtual stenting FFR is estimated based on changes in percent diameter stenosis and the maximum mean blood flow velocity after virtual stent implantation using a multi-scale calculation method.
