N2  - Edge illumination x-ray phase-contrast tomography
(EIXPCT) is an emerging x-ray phase-contrast tomography
technique for reconstructing the complex-valued x-ray refractive
index distribution of an object. Conventional image
reconstruction approaches for EIXPCT require multiple
images to be acquired at each tomographic view angle.
This contributes to prolonged data-acquisition times and
elevated radiation doses, which can hinder in vivo applications.
In this work, a new ?single-shot? method is proposed
for joint reconstruction (JR) of the real and imaginaryvalued
components of the refractive index distribution from
a tomographic data set that contains only a single image acquired
at each view angle. The proposed method is predicated
on a nonlinear formulation of the inverse problem that is
solved by using a gradient-based optimization method.
The method is validated and investigated using computersimulated
and experimental EIXPCT data sets.
