    摘要: Exemplary embodiments of systems and methods can be provided which can generate data associated with at least one portion of a sample. For example, at least one first radiation can be forwarded to the portion through at least one optical arrangement. At least one second radiation can be received from the portion which is based on the first radiation. Based on an interaction between the optical arrangement and the first radiation and/or the second radiation, the optical arrangement can have a first transfer function. Further, it is possible to forward at least one third radiation to the portion through such optical arrangement (or through another optical arrangement), and receive at least one fourth radiation from the portion which is based on the third radiation. Based on an interaction between the optical arrangement (or the other optical arrangement) and the third radiation and/or the fourth radiation, the optical arrangement (or the other optical arrangement) can have a second transfer function. The first transfer function can be at least partially different from the second transfer function. The data can be generated based on the second and fourth radiations.

    摘要: Exemplary method and apparatus for diagnosing or characterizing an inflammation within an anatomical structure can be provided. For example, using at least one source arrangement, it is possible to provide at least one first electro-magnetic radiation to the anatomical structure at at least one first wavelength in vivo. With at least one detector arrangement, it is possible to detect at least one second electro-magnetic radiation at at least one second wavelength provided from the anatomical structure. The second radiation can be associated with the first radiation, and the first wavelength can be shorter than the second wavelength. The second radiation can be provided from the anatomical structure due to at least one change in the anatomical structure caused by the inflammation without providing an artificial fluorescence substance. At least one computer arrangement can be used to determine at least one characteristic of the structure based on the second radiation to diagnose or characterize the inflammation within the anatomical structure.

    摘要: An apparatus for determining a shape of a luminal sample including: a catheter including a lens, the catheter disposed within a strain-sensing sheath such that the lens rotates and translates; a structural imaging system optically coupled to the catheter; a strain-sensing system optically coupled to the catheter; and a controller coupled to the strain-sensing system and the structural imaging system. The controller determines: a first position of the catheter relative to the luminal sample at a first location within the strain-sensing sheath; a second position of the catheter relative to the luminal sample at a second location within the strain-sensing sheath; a first strain of the strain-sensing sheath at the first location; a second strain of the strain-sensing sheath at the second location; a local curvature of the luminal sample relative to the catheter; a local curvature of the catheter; and a local curvature of the luminal sample.
