A computer accessible medium for determining information associated with at least one portion of an anatomical structure, and providing thereon a software program, which, when executed by a processing arrangement, is operable to perform the procedures comprising:
- detecting 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;
- generating three-dimensional volumetric data for the at least one portion as a function of the interference;
- and
- determining 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.
