Abstract
Devices, methods, and systems are provided for analyzing lung imaging data. A server computing device receives imaging data of a lung over a network from a client computing device and analyzes the imaging data to identify lung, airways, and blood vessels, segment the lung into lobes, subtract airways, calculate volumes, calculate emphysema scores, identify fissure locations, calculate fissure completeness scores. A reconstruction of the fissures indicating locations where the fissures are incomplete and a report comprising fissure scores, volumes, and emphysema scores are created.
Claims27
A method for analyzing computerized tomography data of a lung, the method comprising:
- receiving by a server computing device anonymized computerized tomography data of a lung over a network from a client computing device at a different location;
- analyzing the computerized tomography data, wherein analyzing the computerized tomography data comprises
- identifying the lung, airways, and blood vessels;
- segmenting the lung into five separate lobes;
- subtracting airways until at least the third generation;
- calculating volumes of the lobes;
- calculating emphysema scores for the lobes based on density masks;
- identifying fissure locations;
- calculating a fissure completeness score for each fissure, wherein the fissure completeness score of the right upper lobe is based on the completeness of the horizontal fissure and the portion of the right oblique fissure that separates the right upper lobe from the right lower lobe, and wherein the fissure completeness score of the right middle lobe is based on the completeness of the horizontal fissure and the portion of the right oblique fissure that separates the right middle lobe from the right lower lobe;
- creating a three-dimensional reconstruction of the fissures indicating locations where the fissures are incomplete;
- and
- creating a report comprising fissure completeness scores, volumes, and emphysema scores for each lobe.
