Optical Coherence Elastography
S ince the days of Hippocrates, as early as 400 B.C.E., physicians have used palpation—probing by touch—to identify diseased tissue by variations in its mechanical properties. In the modern clinic, the uses of palpation range from assessment of skin lesions to the guidance of the surgical excision of tumors. Indeed, the usefulness of palpation has, over the past 25 years, given rise to a new family of imaging techniques—known as elastography—that map the spatial variation of the mechanical properties of diseased tissue, with greater accuracy and often much higher resolution than can be achieved ...
