Abstract: Exemplary embodiments of apparatus, system and method can be provided to measure a flow of fluid within an anatomical structure. For example, it is possible to use at least one first probe arrangement structured to be insertable into a vessel and configured to direct at least one radiation to at least one portion of the anatomical structure. Further, it is possible to provide at least one second arrangement which configured to detect an interference between a first radiation provided from the fluid via the probe arrangement and second a second radiation provided from a reference path as a function of wavelength thereof. Further, at least one third arrangement can be provided which is configured to determine at least one characteristic of the fluid as a function of the interference.

Abstract: An endoscopic imaging device (e.g., a catheter) comprises a light-transmitting tubing, at least one optical fiber disposed in the light-transmitting tubing, and at least one metalens. The metalens is optically coupled to the optical fiber and is configured to focus light from the optical fiber, through the light-transmitting tubing, and to a target point located outside of the light-transmitting tubing. The metalens includes a plurality of nanostructures. The nanostructures define a phase profile that corrects astigmatism caused by the light-transmitting tubing.

Abstract: In accordance with exemplary embodiments of the present disclosure, device and method can be provided which can facilitate imaging of biological tissues, e.g., luminal organs in vivo, using optical techniques. The exemplary device can include different designs an features of one or more catheters, which can illuminate the tissues, and collect signals from the inside of the lumen. In another exemplary embodiment according to the present disclosure, a balloon-catheter can be provided with the flexible neck, which can absorb most of the bending. According to still another exemplary embodiments of the present disclosure, a balloon-catheter tethered capsule can be provided, and according a yet further exemplary embodiment, a structured balloon design can be provided with one or more protuberances, thus enabling imaging of the structures in close contact, e.g., without compressing of the tissue.

Abstract: Exemplary apparatus and method can be provided. For example, with at least one first arrangement, it is possible to provide at least one first radiation, which can impact at least one second arrangement that is provided in an optical path between the at least one first arrangement(s) and at least sample. The second arrangement can have at least one birefringent property, In addition, with at least one detector third arrangement, it is possible to receive at least one second radiation from at least one first portion of the second arrangement(s), and at least one third radiation from at least one second portion of the second arrangement(s). The second and third radiations can be associated with the first radiation(s). Using at least one computing fourth arrangement, it is possible to determine information regarding the first radiation(s) based on the second and third radiations.

Abstract: Method, apparatus and arrangement according an exemplary embodiment of the present invention can be provided for analyzing and/or illustrating at least one portion of an anatomical structure. For example, light can be forwarded to such portion so as to generate first information which is related to the portion. For example, the light can be provided on or within a subject. The first information can be received, and at least one section of the portion may be selected based on the first information so as to generate second information. A magnification of a display of the portion may be progressively modified as a function of the second information.
