1. A system for determining information associated with at least one portion of an anatomical structure, comprising: at least one arrangement configured to: a. detect 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, b. generate three-dimensional volumetric data for the at least one portion as a function of the interference, and c. determine the information based on the volumetric data and at least one of (i) a spatial distribution or (ii) a temporal distribution of an intensity of the interference.
