Gridrec-MS: an algorithm for multi-slice tomography

Opt Lett. 2019 May 1;44(9):2181-2184. doi: 10.1364/OL.44.002181.

Abstract

Advances in imaging systems and modeling allow for depth information to be retrieved from projections via virtual sectioning of the imaged object. Here we introduce a regridding method that explicitly and directly incorporates this information into a general and non-iterative tomographic reconstruction algorithm. The method is applicable to any imaging scheme that provides depth-resolved projections. Additionally, we show, via numerical simulations, that with this method the required number of projections for adequate angular sampling can be reduced.
