Abstract

We investigate an algorithm for boundary-enhanced image reconstruction from limited-angle projection data in X-ray phase-contrast tomography. The algorithm exploits the fact that the imaging model of phase-contrast tomography establishes a sparse representation of the object that facilitates accurate image reconstruction form highly incomplete measurement data. The developed algorithm may therefore benefit a wide range of X-ray phase-contrast tomography applications by dramatically reducing data-acquisition times and limiting radiation dose.
