The invention provides a 
visualization calculation method for a whole intracranial 
aneurysm interventional therapy stent implantation process, establishes a 
stent release expansion model, provides an effective numerical 
simulation method for the intracranial 
aneurysm interventional therapy stent implantation, and provides a 
visualization method used for detection, calculation and analysis of the 
surgical planning of intracranial 
aneurysm interventional therapy. The adopted technical scheme is as follows: firstly, a 
blood vessel centerline is utilized to 
implant a numerical 
simulation stent into the 
blood vessel, and an 
active contour model is utilized to perform stent expansion, then the distance of each two nodes of the stent is changeless through optimization, and finally 
hemodynamics calculation and analysis are performed, and optimal configuration for 
stent implantation is simulated and calculated. The image 
simulation method can be directly applied to three-dimensional vascular 
angiography tomographic images, enables the stent to keep own geometric morphological characters through optimization, and can utilize 
weight adjustment to enable the stent to be clung to the 
blood vessel wall as far as possible. The simulation process can control the 
stent implantation position conveniently, and better clinical application value is achieved in the 
surgical planning of interventional therapy.
