Abstract

A method and system for editing a lumen contour of a tomographic image. A method comprises: receiving image data corresponding to a plurality of tomographic images acquired by an imaging catheter scanning a blood vessel; obtaining, by a processor, an automatically-generated lumen contour of the blood vessel from a tomographic image of the blood vessel; displaying, on a display, the automatically-generated lumen contour overlaid on the tomographic image of the blood vessel; identifying a true lumen edge of the blood vessel in the tomographic image; estimating a percentage of matching between a shape of the automatically-generated lumen contour to a shape of the true lumen edge; and receiving editing operations from a user via a touchscreen interface for editing at least part of the automatically-generated lumen contour based on the estimated percentage of matching. Plural editing modes are available based on the percentage of matching meeting one or more thresholds.
