AI Technical Summary

Technical Problem

In existing technologies, stent selection mainly relies on the doctor's clinical experience, lacking a systematic assessment of vascular morphology, stent mechanical properties, and postoperative hemodynamics, resulting in poor stent implantation outcomes. Furthermore, virtual simulation calculations are time-consuming, making it difficult to achieve real-time feedback and accurate stent selection.

Method used

By acquiring target image data of cerebral blood vessels for three-dimensional reconstruction, the radius curve and stenosis parameters before expansion are generated, a multi-layer biomechanical model is established, and the balloon expansion process is simulated by mathematical interpolation to select stent models that match the radial support force distribution curve.

Benefits of technology

This approach improves the accuracy and computational efficiency of stent selection, provides quantitative reference data, helps enhance the reliability and standardization of surgery, and avoids complications caused by improper stent selection in traditional methods.
