A one-dimensional fluid simulation method of branching narrow vessel for real-time angiography simulation.

This paper proposes a one-dimensional fluid simulation method for real-time simulation of the contrast medium in a narrow blood vessel. A narrow vessel is modeled with the branches organized in a hierarchy. The density of the contrast medium on each branch is computed using the one-dimensional fluid model. The density at the last point of branch is conveyed to the first point of the following branches. The position of the density computation is determined to continuously convey the simulation results from a large vessel to a narrow vessel. The average computation time with the proposed method is 16.18 ms that is less than 21.25 ms of the particle-based method.
