No.: 13/444,418 that it repeatedly reflects off of the inner surface of the tubular structure along the length thereof. The method further com (22) Filed: Apr. 11, 2012 prises receiving the reflected beam at a second end of the tubular structure. The method still further comprises measur Related U.S. Application Data ing a value of the reflectance of the received reflected beam, defining a parameter value using the measured value, and (60) Provisional application No. 61/535,036, filed on Sep. comparing the parameter value with a predetermined thresh 15, 2011. old value. The method further comprises determining, based on the comparison, the extent to which the inner surface of the Publication Classification tubular structure is contaminated, and displaying an indica tion representative of the contamination based on the deter (51) Int.
