13 March 2009Boundary reconstruction in limited-angle x-ray phase-contrast tomography
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.
