Abstract
A method for estimating the location of an anatomical structure in an x-ray image of a patient obtains the x-ray data in digital format. The method estimates the location of at least a first benchmark feature within the x-ray image according to the obtained digital x-ray data and defines a region of interest within the image according to the estimated location of at least the first benchmark feature. A region of interest for the anatomical structure is searched using a template. The location of the anatomical structure on a display according to the template searching results is highlighted.
Claims16
A method for estimating the location of an anatomical structure in an x-ray image of a patient, comprising:
- obtaining the x-ray data in digital format;
- estimating the location of at least a first benchmark feature within the x-ray image according to the obtained digital x-ray data;
- defining a region of interest within the image according to the estimated location of at least the first benchmark feature;
- searching the region of interest for the anatomical structure using a template;
- and
- highlighting the location of the anatomical structure on a display according to the template searching results.
A method for estimating the location of an anatomical structure in a diagnostic image of a patient, comprising:
- obtaining the x-ray data in digital format;
- detecting a first benchmark feature within the x-ray image;
- detecting a second benchmark feature within the x-ray image;
- locating an intersection between a first line that extends along the length of the first benchmark feature and a second line that extends through a central point related to the curvature of the second benchmark feature and that intersects with the first line at an angle that is within a predetermined range of angles;
- identifying the location of the anatomical structure relative to the intersection;
- defining a region of interest according to the identified location;
- searching the defined region of interest using a template;
- and
- highlighting the location of the anatomical structure on a display according to the template searching results.
A method for estimating the location of an anatomical structure in an x-ray image of a patient, comprising:
- obtaining the x-ray data in digital format;
- estimating a first location of a first benchmark feature within the x-ray image according to the obtained digital x-ray data;
- estimating a second location of a second benchmark feature within the x-ray image according to the obtained digital x-ray data;
- defining a region of interest within the image according to the estimated first and second benchmark feature locations;
- searching the region of interest for the anatomical structure using a template;
- and
- highlighting the location of the anatomical structure on a display according to the template searching results.
A method for estimating the location of the carina in a chest x-ray image of a patient, comprising:
- obtaining the chest x-ray data in digital format;
- estimating a first location of an aortic arch as a first benchmark feature within the x-ray image according to the obtained digital x-ray data;
- estimating a second location of a second benchmark feature within the x-ray image according to the obtained digital x-ray data;
- defining a region of interest within the image according to the estimated first and second benchmark feature locations;
- searching the region of interest for the carina using a template;
- and
- highlighting the location of the carina on a display according to the template searching results.
