By using algebraic geometry tools, the Voronoi algorithm could be effectivelly implemented as a building block of a general 3D reconstruction tool. The presented work show the versatility of the approach, and hint to the complexity of the true 3D problems when compared to the 2D counterparts. Whenever the hardware limitations are met (limited slew rates, waveform memory) the K-space trajectory could deviate from the theoretical form. The 3D Voronoi decomposition offers a natural framework to address those imprecision. Also, the description of the aliasing patterns could be better understood in the same framework.
