Lower bounds for the truncated Hilbert transform
R Alaifari, LB Pierce, S Steinerberger - Revista matemática …, 2016 - ems.press
Given two intervals I, J⊂ R, we ask whether it is possible to reconstruct a real-valued
function f∈ L2(I) from knowing its Hilbert transform Hf on J. When neither interval is fully …

Interior tomographic imaging of mouse heart in a carbon nanotube micro-CT
BACKGROUND: The relatively high radiation dose from micro-CT is a cause for concern in
preclinical research involving animal subjects. Interior region-of-interest (ROI) imaging was …

Stability estimates for the regularized inversion of the truncated Hilbert transform
In limited data computerized tomography, the 2D or 3D problem can be reduced to a family
of 1D problems using the differentiated backprojection method. Each 1D problem consists of …
