Effectiveness of Torus CT for practical X-ray data

Determine how effectively the Torus CT method can be applied to practical X-ray data.

Background

The paper studies the practical implementation of the Torus CT method, a Fourier-based reconstruction framework for the geodesic X-ray transform on the two-dimensional torus. Although the foundational work established theoretical inversion results and demonstrated the method numerically, its performance on experimentally acquired X-ray measurements had not been established. The authors identify the effectiveness of applying Torus CT to practical data as unresolved and address it through experiments with fan-beam X-ray measurements of a walnut.
