Pore size distribution estimation using the mixing time dependency of a double diffusion encoding experiment: a proof of concept from Monte Carlo simulated data

Double diffusion encoding (DDE) MR [1] is sensitive to the dimension of microscopical pores [2]. The aquired signal (S) depends on the angle (ψ) and delay (mixing time: t m ) between the two diffusion encodings [1,3] (Figure 1). We study the t m -dependency as a way to estimatimate spherical pore radii.
