Problems solved by technology

[0008] This manual process is relatively time-consuming, especially for untrained users
Also, the procedure does not always produce the best results because it is difficult to manually locate points at the precise ends of vessel branches
As a result, such vascular branching may not be fully visualized

Embodiment Construction

[0024] Technical effects of some configurations of the present invention include providing an automated workflow that provides visualization of branches in the aorta. Likewise, some configurations of the invention provide for automated analysis of other vessels, such as coronary vessels. Automated workflows in some configurations provide or facilitate the removal of bone from 3D CT images, volume analysis to precisely determine the origin and end points of each branch of the artery, and tree analysis to display the central line and quantitative representation of vessels ( That is, the minimum and maximum diameter). In some configurations of the invention, bone removal is provided using the known "auto-bone" procedure, and tree analysis is provided through the known auto-tracking procedure.

[0025] Some configurations of the invention utilize a volumetric analysis program that receives as input the vessel tree volume (where bone and gas has been removed) and produces as outpu...

Abstract

A method for selecting and / or labeling a vessel image includes operating an imaging system to obtain reconstructed image data including a volume having vessels therein. A bone removal routine is then applied to the reconstructed image data to produce a bone-free image. An initial point on a main vessel in the bone-free image is located, and bifurcation points and branches departing from the main vessel are identified. An adjacency graph of each branch coming from the main vessel is built. The method includes either or both of selecting and displaying a best or at least a favorable path through the vessels in accordance with predetermined criteria using the adjacency branch, or labeling and displaying branches of the main vessel.

Description

technical field [0001] The present invention generally relates to methods and devices for analyzing and displaying tube branching. Background technique [0002] Cross-reference related applications [0003] This application claims priority to US Provisional Application No. 60 / 630,884, filed November 24, 2004, entitled "Methods and apparatus for selecting and / or labeling vessel branches," which is incorporated herein by reference in its entirety. [0004] Identifying and labeling the different branches of blood vessels from computed tomography (CT) images is a routine task that can take valuable time that could be better spent analyzing and diagnosing these vessels. [0005] Known procedures for labeling and analyzing vessel branches include manually locating a point on the image of each branch end using a computer with a display and a user pointing device such as a mouse, trackball or keyboard keys. After this selection, the computer runs a program that displays each vesse...
