IMAGE PROCESSING SYSTEM FOR DISPLAYING INFORMATION RELATING TO PARAMETERS OF A 3-D TUBULAR OBJECT

摘要

An image processing system, for processing a 3-D image of a 3-D substantially tubular structure (AAA), formed of a lumen (LUM) limited by a wall (5,6), comprising processing means (102) for segmenting the 3-D external or internal surface of the structure; estimating a local parameter such as the local wall thickness (T) or diameters; and display means (105) for displaying the 3-D surface of segmentation with zones colorized according to a color code, so that to indicate the local parameter values in said zones. The system may comprise processing means to generate (107) a 3-D virtual cylinder and projecting (108) the color-coded 3-D segmentation surface onto the 3-D virtual cylinder surface colorized according to the same color-code; and projecting the 3-D virtual cylinder surface onto a 2-D color-coded map; and display means for displaying the 2-D color-coded map with colorized zones indicating the local parameter values (T) in said zones (109).
