The reconstruction of three-dimensional images in x-ray computed tomography using holographic methods

The article investigates the version of solution of the inverse problem of X-ray tomography for reconstructing the internal structure of macroscopic objects using holographic methods for visualization of volumetric images. Considered the following solution: tomographic reconstruction of the internal structure of the object sections in X-rays (absorption index) based on the two-dimensional Radon transform, with subsequent obtaining holograms of these sections for optical three-dimensional image reconstruction (for macroscopic objects). To solve the problem, there was numerical simulation to obtain tomograms of the mathematical phantom in developed programmatic reconstructor of tomographic images with subsequent receipt of digital holograms of these layers and synthesis of volumetric image from these layers. Researches have shown the possibility of obtaining volumetric images based on the tomographic reconstruction of the internal structure of the object sections in X-rays (absorption index) using two-dimensional Radon transform followed by obtaining digital holograms of these sections.
