    Area of Science:

    • Biomedical Engineering
    • Medical Simulation
    • Computational Fluid Dynamics

    Background:

    • Accurate guidewire simulation is crucial for effective virtual vascular intervention training.
    • Previous models often neglect the significant influence of blood flow dynamics.

    Purpose of the Study:

    • To develop a novel guidewire simulation model that integrates blood flow analysis.
    • To enhance the physical credibility of guidewire behavior simulation in virtual training environments.

    Main Methods:

    • Computed blood flow distribution using Poiseuille Law for discrete cylindrical vessels.
    • Integrated blood flow computation into a Kirchhoff rods model.
    • Validated the simulation using a 3D printed vascular phantom and electromagnetic tracking (EMT).

    Main Results:

    • The blood flow-affected model demonstrated superior physical credibility.
    • Achieved a lower and more stable root-mean-square (RMS) error of 2.14mm ± 1.24mm.
    • Outperformed the traditional Kirchhoff model, which had an RMS error of 4.81mm ± 3.80mm.

    Conclusions:

    • Integrating blood flow significantly improves guidewire simulation accuracy.
    • The proposed model enhances the realism of virtual vascular interventions.
    • Real-time simulation at over 30 fps is achievable with hardware acceleration.
