Abstract: A method and apparatus for determining properties of a tissue or tissues imaged by optical coherence tomography (OCT). In one embodiment the backscatter and attenuation of the OCT optical beam is measured and based on these measurements and indicium such as color is assigned for each portion of the image corresponding to the specific value of the backscatter and attenuation for that portion. The image is then displayed with the indicia and a user can then determine the tissue characteristics. In an alternative embodiment the tissue characteristics is classified automatically by a program given the combination of backscatter and attenuation values.

Abstract: In part, the invention relates to a single clad fiber to multi-clad optical fiber connector for use in applying excitation light to a sample and obtaining reflected light from the sample. The connector can include a dual clad optical fiber portion and a single clad optical fiber portion in optical communication with the dual clad optical fiber portion. In one embodiment, a core of the dual clad optical fiber portion and a core of the single clad optical fiber portion have substantially similar indices of refraction. In one embodiment, excitation light is propagated by the core of the dual clad optical fiber. Further, in one embodiment, light reflected by the sample is propagated by the first cladding layer of the dual clad optical fiber portion.

Abstract: In one embodiment, the invention relates to a processor based method for generating positional and other information relating to a stent in the lumen of a vessel using a computer. The method includes the steps of generating an optical coherence image data set in response to an OCT scan of a sample containing at least one stent; and identifying at least one one-dimensional local cue in the image data set relating to the position of the stent.
