Optical Elastography: From Theory to Clinical Applications
Message:
Abstract:
In-vivo evaluating and quantifying the mechanical properties of tissues, particularly the elastic properties of soft tissues, which have been of increasing interest for many medical applications for the past two decades, by utilizing conventional measurement methods are difficult. Elastography is a promising imaging modality for in-vivo tissue characterization. It was proposed to be utilized for breast cancer detection on the basis of tissue hardness being indicative of the presence of a tumor as the practice of palpation examination would indicate. The new imaging technique "Optical Elastography" has the potential as a clinical tool for in-vivo assessing the stiffness of biological tissues. In this paper, we briefly discuss the results of almost a-decade investigations in the field of optical elastography. We present the basic principles and limitations that are involved in the production of elastograms of biological tissues. We conclude the paper with the review of potential applications of this technique for medical diagnosis. We also discuss some fields in which much progress has yet to be made in order for optical elastography to become a viable clinical tool. The usefulness of this technology and the new information it provides suggest that it might soon be available as a commercial system.
