Abstract
Methods and apparatuses for identifying lung features are provided herein.
Claims20
A method of determining segment boundaries of lung segments, the method comprising:
- receiving image data forming a three-dimensional representation of at least a part of a lung, wherein the lung is divided into multiple lung lobes, wherein each lobe is divided into multiple lung segments;
- computationally identifying, using the image data, at least one anatomical feature within the lung, wherein the at least one anatomical feature comprises one or more of the following:
- a network of arteries, a network of veins, a network of airways, some or all of lung parenchyma, and one or more fissures of the lung;
- computationally identifying, using the at least one anatomical feature, all segment boundaries of at least one lung segment within the lung, wherein the segment boundaries comprise surfaces between the at least one lung segment and adjacent lung segments;
- and
- generating a representation of all or part of the lung showing the segment boundaries of the at least one lung segment within the lung.

A method of identifying segment boundaries of lung segments, the method comprising:
- receiving image data forming a volumetric representation of at least a part of a lung, wherein the lung is divided into multiple lobes, wherein each lobe is divided into multiple lung segments;
- computationally identifying, using the image data, a network of arteries;
- computationally identifying, using the image data, a network of bronchi;
- computationally identifying, using the image data, a network of veins;
- and
- computationally identifying, based on the identified network of arteries, network of bronchi, and network of veins, segment boundaries of a plurality of lung segments within at least one lobe of the lung, wherein the segment boundaries comprise surfaces between adjacent lung segments.
