在边界上的凸度假设下,我们解决了局部逆问题,即表明,地球X射线变换可以以稳定的方式局部倒置。一个甚至具有重建公式。我们还表明,在严格凸出的超曲面的假设下,地球X射线变换是全球注入性的。此外,我们证明了稳定性估计,并提出了用于重建的层剥离类型算法。
Under a convexity assumption on the boundary we solve a local inverse problem, namely we show that the geodesic X-ray transform can be inverted locally in a stable manner; one even has a reconstruction formula. We also show that under an assumption on the existence of a global foliation by strictly convex hypersurfaces the geodesic X-ray transform is globally injective. In addition we prove stability estimates and propose a layer stripping type algorithm for reconstruction.
