SEARCH FOR AN OPTIMAL SOLUTION OF THE PROBLEM OF ARTERIOVENOUS MALFORMATION EMBOLIZATION BY THE PARTICLE SWARM METHOD

The joint flow of blood and embolization composition inside an arteriovenous malformation is modeled with the use of a one-dimensional model of two-phase filtration based on real clinical data. Numerical simulations are performed by a monotonic modification of the CABARET scheme. Optimal regimes of...

Description
Summary:The joint flow of blood and embolization composition inside an arteriovenous malformation is modeled with the use of a one-dimensional model of two-phase filtration based on real clinical data. Numerical simulations are performed by a monotonic modification of the CABARET scheme. Optimal regimes of embolization for real patients are found with the use of a modified particle swarm method, which is a numerical method of global optimization.
