We are sharing scripts for modeling the dependence of diffusion on diffusion time, D(t), within permeable anisotropic microstructure of biological tissue.
The random permeable barrier model (RPBM) characterizes “disordered” microstructure. RPBM has been identified as a powerful tool for describing the mezoscopic structure of muscle tissue. The model has been used in vivo for quantification of muscle myofiber diameter and sarcolemma membrane permeability, among other applications.
