Tomographic Particle Image Velocimetry (Tomo-PIV) is a promising new PIV technique. However, its high computational costs often make time-resolved measurements impractical. In this paper, a new preprocesseing technique is tested experimentally for the first time on a simple vortex ring. The new method produces very similar velocity and vorticity distributions to the standard iterated solution, at a fraction of the computational cost. Therefore, through this new technique, the processing of thousands of vector fields required for turbulent statistics can be made significantly more affordable; an important step in the development of Tomo-PIV.
