Abstract:
1. An apparatus for obtaining information associated with at least one plaque structure, comprising: at least one arrangement which is configured to receive at least one first electromagnetic radiation at a first wavelength and at least one second electromagnetic radiation at a second wavelength from the at least one plaque structure, wherein the at least one arrangement determines the information as a function of the first and second electromagnetic radiations, wherein a first one of the at least one first electromagnetic radiation is at least partially returned from a first depth of at least one anatomical structure, wherein a second one of the at least one first electromagnetic radiation is at least partially returned from a second depth of the at least one anatomical structure, wherein the first depth is different from the second depth, and wherein the at least one arrangement is configured to determine data associated with a spatial location of the anatomical structure within a sample based on a combination of the first and second ones of the at least one first electromagnetic radiation.
