Abstract

Collageneus tissues manifest strongly pronounced viscoelastic behavior. Namely, viscosity leads to time-dependence of the deformation processes. This concerns both compression (loading) and unloading of the tissue. Both processes can be characterized by a relaxation time - the time during which the strain changes e-times. We demonstrate the applicability of the OCT-based 2D relaxography to characterize local relaxation time of collageneous tissues. The developed technique can be used for further investigation of the viscoelastic properties of healthy and pathological collageneous tissues.
