Randomly generated realistic vessel geometry using spline interpolation and 2D Perlin noise

Abstract

The importance of using artificial vessel walls for examining the effects of the geometry to the risk of plaque rupture, has grown. This has also become essential, mainly because of the lack of an extensive dataset of real vessel geometries that covers an adequate number of cases (e.g. variable amplitude of stenosis for the same vessel). In this paper, we propose a method for creating realistic artificial vessel geometry. The centerline is constructed using PseudoRandom Noise Generator (PRNG) and 3d spline interpolation and the artificial wall using a variation of the 2d Perlin Noise. The resulted geometry indicates that this method achieves realistic representations of vessel walls with user defined parameters.
