1. A method for joining images of an interior surface of a tubular cavity having a longitudinal lumen and an interior wall surface, the method comprising:
- acquiring a first image that has a longitudinal view of the tubular cavity, wherein the longitudinal view includes a view of at least a portion of the lumen and the interior wall surface of the tubular cavity;
acquiring a second image that has a perpendicular view of the tubular cavity, wherein the perpendicular view includes a view of the interior wall surface of the tubular cavity;
flattening the first image; and
