System and method for detecting trachea
First Claim
1. A system for detecting a trachea of a patient, the system comprising:
- an imaging device configured to obtain image data of the patient; and
a computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to;
generate a three-dimensional (3D) model of a chest of the patient based on the image data;
generate slice images of the 3D model along an axial direction;
identify a potential connected component in a first slice image of the generated slice images;
identify a potential connected component in a second slice image of the generated slice images, wherein the second slice image is immediately subsequent to the first generated slice image;
confirm that the potential connected component of the first and second slice images are connected;
label the potential connected component as a connected component;
label the first slice image as a top slice image of the generated slice images;
label the connected component in the top slice image as an active object;
associate each connected component in a current slice image of the generated slice images with a corresponding connected component in a previous slice image based on a connectivity criterion;
label each connected component in the current slice image associated with a connected component of the preceding slice image as the active object; and
identify the active object as the trachea, based on a length of the active object.

Abstract
Disclosed are systems, devices, and methods for detecting a trachea, an exemplary system comprising an imaging device configured to obtain image data and a computing device configured to generate a three-dimensional (3D) model, identify a potential connected component in a first slice image, identify a potential connected component in a second slice image, label the first slice image as a top slice image, label the connected component in the top slice image as an active object, associate each connected component in a current slice image with a corresponding connected component in a previous slice image based on a connectivity criterion, label each connected component in the current slice image associated with a connected component of the preceding slice image as the active object, and identify the active object as the trachea, based on a length of the active object.
