1. A system for quantifying biomechanical properties of tissues in a subject, comprising:
a phase sensitive low coherence interferometry or optical coherence tomography subsystem for imaging the tissues and measuring intrinsic displacements in the tissues resulting from a heartbeat of the subject; and
a data processor programmed with an algorithm for quantifying biomechanical properties of the tissues based on the intrinsic displacements.
