Claim One:
1. A method of automatically identifying a lumen boundary in a vascular image comprising the steps of: collecting data in a blood vessel as a set of scan lines by optical coherence tomography; generating a binary mask using the collected set of scan lines using a computer, wherein the binary mask is generated using an intensity threshold; defining a plurality of scan lines in the binary mask; identifying a region as lumen boundary tissue on each scan line of the plurality of scan lines; defining contour segments in response to the plurality of scan lines and the region of lumen boundary tissue on each scan line of the plurality of scan lines; identifying valid neighboring contour segments in the plurality of scan lines; interpolating missing contour data between valid neighboring contour segments, wherein the valid neighboring contour segments and the interpolated missing contour data define the lumen boundary; and generating the vascular image from the set of scan lines; and displaying the vascular image and the lumen boundary on a display.
