Abstract

Methods and systems for assessing lung function using volumetric images obtained at inspiration and expiration. The method may include processing the first and second set of images to identify known anatomical structures of the lungs, registering the first set of images to the second set of images to match voxels of the first set of images to voxels of the second set of images as matched pairs of inspiratory and expiratory voxels, calculating a continuous probability of a lung characteristic at a location of the matched pairs of voxels, and displaying the result on a display. The method may also include classifying lung tissue at each location as normal, having air trapping without emphysema, or being emphysematous.

Dependent claims

A method of assessing lung function using a first set of lung volumetric images and a second set of volumetric images, the method comprising:

a) registering the first set of images to the second set of images to match voxels of the first set of images to voxels of the second set of images as matched pairs voxels;
b) calculating a probability of a lung characteristic and/or classifying a severity of a lung abnormality at each of a plurality of locations, each of the plurality of locations corresponding to one of the matched pairs of voxels of step a);
and
c) presenting a result of step b) on a display or in a report, the presented result comprising the calculated probability and/or the severity classification of the lung abnormality at each of a plurality of locations of matched pairs of voxels.
