Image display of a tubular structure

摘要

Described herein is a technology for facilitating visualization of a tubular structure. Digitized image data of the tubular structure is received and processed to determine a centerline. A first transformation operation is performed on a first set of coordinates representing the tubular structure to generate a transformed tubular structure with a straight centerline. A second transformation operation is then performed locally on a second set of coordinates representing at least one fold of the transformed tubular structure to generate a transformed fold, which is perpendicular to the centerline.

1. A method performed by a computer system for visualizing a tubular structure, comprising:
(i) receiving digitized image data of the tubular structure; (ii) determining a centerline of the tubular structure; (iii) performing a first transformation operation on a first set of coordinates representing the tubular structure to generate a transformed tubular structure with a straight centerline; (iv) defining a local axis of a fold of the transformed tubular structure, wherein the local axis lies on a dividing plane that divides the fold substantially equally into two portions; and (v) performing a second transformation operation locally on a second set of coordinates representing the fold of the transformed tubular structure to generate a transformed fold, wherein the local axis of the transformed fold is perpendicular to the centerline.
