## Abstract

A system for facilitating imaging of an anatomical structure(s) can be provided, and can include, for example, a substance which can induce a change in the anatomical structure(s) when applied to the anatomical structure(s), and an imaging arrangement which can be configured to generate an image of the anatomical structure(s) based on the change of the anatomical structure(s) when the substance is applied. The imaging arrangement can include an apparatus which can be configured to (i) illuminate the anatomical structure(s) with a first electro-magnetic radiation(s), and (ii) receive a second electro-magnetic radiation from the anatomical structure(s) that can be based on the first electro-magnetic radiation. The change can affect a characteristic(s) of the second electro-magnetic radiation.

## Claims

### Claim 1

A system for facilitating imaging of at least one anatomical structure, comprising:
a substance which induces a change in the at least one anatomical structure when applied; and
an imaging arrangement which is configured to generate an image of the at least one anatomical structure based on the change of the at least one anatomical structure when the substance is applied.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the imaging arrangement further comprising an apparatus which is configured to (i) illuminate the at least one anatomical structure with a first electro-magnetic radiation(s), and (ii) receive a second electro-magnetic radiation from the at least one anatomical structure that is based on the first electro-magnetic radiation, and wherein the change effects at least one characteristic of the second electro-magnetic radiation.

### Claim 3 (depends on 2)
