Lumped parameter bond graph models of cerebral circulation improve simulation speed ~200-fold while preserving accuracy.
A bond graph model of cerebral circulation improves simulation speed by 200-fold while preserving accuracy, enabling clinically feasible real-time systemic blood flow simulations.
Enables real-time cerebral hemodynamics modeling at bedside; leaves open prospective clinical validation before routine use.
The primary paper Safaei et al. (2018) proposed an anatomically detailed model of the human cerebral circulation that runs faster than real-time on a desktop computer and is designed for use in clinical settings when the speed of response is important. Based on a one-dimensional formulation of the flow of an incompressible fluid in distensible vessels, a lumped parameter model was developed for 218 arterial segments. The proposed model improved simulation speed by approximately 200-fold while preserved accuracy. Bond graph formulation was used to ensure mass and energy conservation. The model predicted the pressure and flow signatures in the body.
