Limited angle tomography for transmission X-ray microscopy using deep learning.

Journal of synchrotron radiation Feb 13, 2020
In transmission X-ray microscopy (TXM) systems, the rotation of a scanned sample might be restricted to a limited angular range to avoid collision with other system parts or high attenuation at certain tilting angles. Image reconstruction from such l...
