Abstract
An apparatus for obtaining information regarding a biological structure(s) can include, for example a light guiding arrangement which can include a fiber through which an electromagnetic radiation(s) can be propagated, where the electromagnetic radiation can be provided to or from the structure. An at least partially reflective arrangement can have multiple surfaces, where the reflecting arrangement can be situated with respect to the optical arrangement such that the surfaces thereof each can receive a(s) beam of the electromagnetic radiations instantaneously, and a receiving arrangement(s) which can be configured to receive the reflected radiation from the surfaces which include speckle patterns.
Claims22
A catheter system for obtaining information regarding at least one biological sample, comprising:
- at least one fiber through which at least one electromagnetic radiation is propagated to the at least one biological sample;
- a multi-faceted mirror having multiple surfaces arranged with respect to the at least one fiber to simultaneously receive the at least one electromagnetic radiation at each of the multiple surfaces and deliver reflected radiation that includes speckle patterns;
- and
- a fiber bundle configured to receive, from the multi-faceted mirror, a reflected radiation that includes the speckle patterns from the multiple surfaces of the multi-faceted mirror,
- wherein the fiber bundle is further configured to deliver the reflected radiation obtained, via the multiple surfaces of the multi-faceted mirror, from the at least one biological sample at multiple illumination locations to a detector to image the speckle patterns from the at least one biological sample at the multiple illumination locations based on the reflected radiation.
A catheter system for obtaining information regarding an in-vivo vessel, comprising:
- at least one fiber through which light is propagated to the in-vivo vessel;
- a reflector having multiple surfaces and arranged with respect to the at least one fiber to simultaneously receive the light at each of the multiple surfaces and simultaneously deliver reflected light that induces speckle patterns in the in-vivo vessel that are directed back to the reflector;
- and
- a fiber bundle configured to receive, from the reflector, the speckle patterns induced by the reflected light that includes the speckle patterns induced by the reflected light from the multiple surfaces of the reflector, wherein the fiber bundle is further configured to deliver the reflected light obtained, via the multiple surfaces of the reflector, from over a circumference of the in-vivo vessel to a detector to image the speckle patterns from the circumference of the in-vivo vessel based on the reflected light.
