A Software Component Approach for GPU Accelerated Physics-Based Blood Flow Simulation

High-fidelity patient specific model for blood flow simulation is important in medical applications. In this paper, a software component approach is proposed to perform physics based simulation of blood flow using GPU for general computing. The method comprises three independently developed software components, namely image processing component, object model component and GPU acceleration component. The fluid dynamics of blood flow is simulated using a mesh free modeler based on an improved Smoothed Particle Hydrodynamics method, and the interaction with arterial wall is simulated using a Finite Element modeler based on lumped element approach. Real-time simulation of blood flow has been demonstrated in an application on patients with abdominal aorta aneurysm. The internal fluidic structure and pressure distribution analysis have also been achieved using the proposed method.
