Title:
METHOD AND STORAGE MEDIUM FOR PRECISE ACQUISITION OF STENOTIC LESION RANGE
Document Type and Number:
WIPO Patent Application WO/2022/109907
Kind Code:
A1
Abstract:
Provided are a method and storage medium for the precise acquisition of a stenotic lesion range, comprising: performing three-dimensional modeling according to a real-time vessel diameter Dt, a vessel centerline length L, and a stenosis range to form a mathematical model having a narrow lesion range (S100); preliminary determination to obtain a first stenotic lesion range (S200); removing erroneously determined stenotic regions from the first stenotic lesion range to obtain a second stenotic lesion range (S300). In the method and storage medium for the precise acquisition of a stenotic lesion range, by means of modeling a vascular wall in three dimensions after refitting, and further correcting for coarse-precision vascular stenosis, the accuracy of a narrow lesion range is ensured.
