Keywords: Signal Modeling, Diffusion/other diffusion imaging techniquesIn 1966, Kac asked the question ‘Can one hear the shape of a drum?’ which refers to linking the density of states function to the shape of the pores. We illustrate how the density of eigenstates as well as the pore shape can be obtained through diffusion measurements performed via a recently introduced arrangement of long and narrow gradient pulses. In the presence of dispersity, maps derived from the signal provide exquisite details about the ensemble of pore shapes within the voxel.
