Document Type and Number:
WIPO Patent Application WO/2021/135058
Kind Code:
A1
Abstract:
An evaluation method and system for a corrosion degree of an absorbable stent. The method comprises the following steps: obtaining the total number S0 of stent bars of the absorbable stent at the time zero of implantation (S10); separately obtaining n frames of OCT images of the absorbable stent at the time x of implantation, wherein x is greater than 0, and n is a natural number greater than 1 (S20); according to the n frames of OCT images, determining the total number Ni of the stent bars corresponding to each frame of OCT image, wherein i is a natural number greater than or equal to 1, and is less than or equal to n, and calculating the total number Sx, (I) of the stent bars corresponding to the n frames of OCT images at the time x of implantation (S30); determining the corrosion degree Cij of a jth stent bar in an ith frame of OCT image at the time x of implantation, wherein j is a natural number greater than or equal to 1, and is less than or equal to Ni (S40); and calculating the overall corrosion degree Cx of the absorbable stent at the time x of implantation according to the following formula (II) (S50). The evaluation method can be applied to clinical treatment.
