By diffusion
pore imaging, the average shape of arbitrary closed pores in an imaging volume
element can be detected employing a long-narrow gradient profile. Alternative approaches
use short gradient pulses only. Until now, however, diffusion pore imaging of
non-point-symmetrically shaped pores has not been demonstrated using short
gradient pulses only. In this abstract, we present a first experimental verification
using double diffusion encoded experiments. Non-point-symmetric pores result in
non-vanishing imaginary parts in the double diffusion encoded signal. Thus the phase
of the form factor can be estimated with an iterative approach. This allows for
unambiguous pore image reconstruction.
