Abstract
Angiography is a minimally invasive diagnostic procedure in endovascular interventions.
Training interventional procedures is a big challenge, due to the complexity of the procedures
with the changes of measurement and visualization in blood flow rate, volume, and image
contrast. In this paper, we present a novel virtual reality-based 3D interactive training platform for
angiography procedure training. We propose a multi-fluid flow approach with a novel corresponding
non-slip boundary condition to simulate the effect of diffusion between the blood and contrast
media. A novel syringe device tool is also designed as an add-on hardware to the 3D software
simulation system to model haptics through real physical interactions to enhance the realism of the
simulation-based training. Experimental results show that the system can simulate realistic blood
flow in complex blood vessel structures. The results are validated by visual comparisons between
real angiography images and simulations. By combining the proposed software and hardware, our
system is applicable and scalable to many interventional radiology procedures. Finally, we have
tested the system with clinicians to assess its efficacy for virtual reality-based medical training.
