First Claim
1. An apparatus for obtaining information for at least one anatomical structure, comprising:
- at least one radiation providing first arrangement configured to forward at least one first electro-magnetic radiation to and impact the at least one anatomical structure which is external from the apparatus;
at least one detector second arrangement configured to detect at least one second electro-magnetic radiation provided from at least one portion within the at least one anatomical structure which is based on the at least one first electro-magnetic radiation; and
at least one computer third arrangement configured to (i) determine at least one characteristic of the at least one anatomical structure based on the at least one second electro-magnetic radiation, and (ii) obtain data relating to a pressure of the at least one portion of the at least one anatomical structure based on the at least one characteristic,wherein the at least one characteristic is a speckle pattern of the at least one portion.

Abstract
Exemplary apparatus and method for obtaining information for at least one structure can be provided. For example, it is possible to forward at least one first electro-magnetic radiation to the at least one structure which is external from the apparatus. At least one second electro magnetic radiation provided from the at least one structure (which is based on the first electro-magnetic radiation(s)) can be detected. It is also possible to determine at least one characteristic of the structure(s) based on the second electro-magnetic radiation(s), and obtain data relating to a pressure of at least one portion of the structure(s) based on the characteristic(s).
