Abstract

A system, arrangement, computer-accessible medium and process are provided for determining information associated with at least one portion of an anatomical structure. For example, an interference between at least one first radiation associated with a radiation directed to the anatomical structure and at least one second radiation associated with a radiation directed to a reference can be detected. Three-dimensional volumetric data can be generated for the at least one portion as a function of the interference. Further, the information can be determined which is at least one geometrical characteristic and/or at least one intensity characteristic of the portion based on the volumetric data.
