Abstract

Disclosed are systems, devices, and methods for marking a main carina and a trachea of a patient, an exemplary method comprising importing slice images of a chest of the patient, generating a three-dimensional (3D) model based on the imported slice images, displaying the 3D model in a graphical user interface (GUI), locating the main carina by viewing 2D images of the 3D model in an axial orientation, marking the main carina in one of the 2D images of the 3D model, adjusting a view plane of the 3D model around a rotation axis defined by the marked location of the main carina to adjust the view plane from an axial orientation to a coronal orientation while keeping the main carina in the view plane to thereby display the entire trachea on the GUI, and marking an upper end of the trachea in one of the 2D images of the 3D model.

Claims

1. A method for marking a main carina and a trachea of a patient, the method comprising:

importing, into an image processing computer, slice images of a chest of the patient from an imaging device;

generating, by a graphics processor included in the image processing computer, a three-dimensional (3D) model based on the imported slice images;

displaying, by the image processing computer, the 3D model in a graphical user interface (GUI);

displaying, via the GUI, 2D images of the 3D model;

receiving a selection, based on input from a user via the GUI, of the main carina in one of the 2D images of the 3D model;

marking the main carina in one of the 2D images of the 3D model;

adjusting a view plane of the 3D model around a rotation axis defined by the marked location of the main carina to adjust the view plane from an axial orientation to a coronal orientation while keeping the main carina in the view plane to thereby display the entire trachea on the GUI;

receiving a selection, based on input from the user via the GUI, of an upper end of the trachea in one of the 2D images of the 3D model; and

marking the upper end of the trachea in one of the 2D images of the 3D model.

2. A method for marking a main carina and a trachea of a patient, the method comprising:

importing, into an image processing computer, slice images of a chest of the patient from an imaging device;

generating, by a graphics processor included in the image processing computer, a three-dimensional (3D) model based on the imported slice images;

displaying, by the image processing computer, the 3D model in a graphical user interface (GUI);

marking, by a user using the GUI, the main carina in one of a plurality of 2D images of the 3D model;

adjusting, by the user using the GUI, a view plane of the 3D model around a rotation axis defined by the marked location of the main carina to adjust the view plane from an axial orientation to a coronal orientation while keeping the main carina in the view plane to thereby display the entire trachea on the GUI; and

marking, by a user using the GUI, an upper end of the trachea in one of the plurality of 2D images of the 3D model.

3. The method according to claim 2, further comprising, prior to marking the main carina, locating the main carina in one of the 2D images of the 3D model.

4. The method according to claim 3, wherein the user locates the main carina by viewing the 2D images of the 3D model in an axial orientation.

5. The method according to claim 2, wherein the 3D model is generated based on two dimensional images obtained by tomographic technique, radiography, tomogram produced by a computerized axial tomography scan, magnetic resonance imaging, ultrasonography, contrast imaging, fluoroscopy, nuclear scans, or positron emission tomography.

6. The method according to claim 2, wherein adjusting a view plane of the 3D model includes adjusting the view plane around a rotation axis.

7. The method according to claim 6, wherein adjusting the view plane around the rotation axis includes adjusting the view plane from an axial orientation to a coronal orientation.

8. The method according to claim 7, wherein, during the adjusting, the main carina is kept within the view plane.

9. The method according to claim 2, further comprising verifying, by the user using the GUI, the marking of the trachea by reviewing a rendering of the 3D model displayed on the GUI.

10. The method according to claim 9, wherein the rendered 3D model includes the marking of the main carina and the marking of the upper end of the trachea.
