Abstract
An evaluation method and system for the corrosion degree of an absorbable stent. The method includes the following steps: obtaining the total number Sof stent bars of the absorbable stent at the time zero of implantation (S); separately obtaining n frames of optical coherence tomography (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 (S); determining, according to the n frames of OCT images, 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 less than or equal to n; and calculating the total number Sof the stent bars corresponding to the n frames of OCT images at the time x of implantation (I) (S); determining a 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 less than or equal to Ni (S); and calculating an overall corrosion degree Cx of the absorbable stent at the time x of implantation according to the following formula: (II) (S). The evaluation method can be applied to clinical treatment.
