Factors contributing to slice loss in small-angle X-ray scattering tensor tomography in real space

Abstract

X-ray small-angle scattering tensor tomography (SAXSTT) technique is an innovative method that enables 3D tomographic reconstruction of large-volume voxels non-destructively. This study identifies factors that affect slice loss in SAXSTT in real space. Results show that the quality and resolution of the resulting images are strongly influenced by the signal to noise ratio (SNR), absorption, as well as scattering in the sample. In addition, parameters such as collimator and slice thickness during CT scanning prove crucial for obtaining optimal image results. Reconstruction using SAXSTT shows great potential in high-precision material analysis, especially in applications where sample integrity is required to be maintained.
