Method and device for judging lesions of small airway of single lung lobe

Abstract

The invention discloses a method and device for judging lesions of a small airway of a single lung lobe and relates to the field of biomedical engineering. The method comprises the steps of obtaininga first lung lobe segmentation image of a full inspiration phase lung image; obtaining a second lung lobe segmentation image of a full expiration phase lung image; respectively extracting a pluralityof full inspiration phase single lung lobes with CT values in the first lung lobe segmentation image; respectively extracting a plurality of full expiration phase single lung lobes with CT values in the second lung lobe segmentation image; registering the full inspiration phase single lung lobes and the full expiration phase single lung lobes at the corresponding positions to obtain registered full inspiration phase single lung lobes and registered total expiration phase single lung lobes; and respectively comparing the CT values of the registered full inspiration phase single lung lobes and the registered full expiration phase single lung lobes with an inspiration phase set threshold value and an expiration phase set threshold value. The problem that the distribution of the lesions of thesmall airway on specific lung lobes cannot be judged is solved.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a single lobe small airway lesion judgment method and device. Background technique [0002] Artificial intelligence diagnosis and analysis for the respiratory specialist medical consortium is an important part of precision medicine, and the cloud communication and interaction between the respiratory department and radiologists is an inevitable trend towards the online era and hierarchical diagnosis and treatment. Chronic obstructive pulmonary disease (COPD), a progressive lung disease, is projected to become the third leading cause of death globally by 2030. Functional small airway disease (functional small airways disease, fSAD) is an airway with a diameter of less than 2-3 mm, about the fourth-grade terminal bronchiole and respiratory bronchiole, and the small airway resistance accounts for a small proportion of the total airway resistance in normal people , while the sma...

Problems solved by technology

[0006] In view of this, the present invention provides a method and device for judging small airway lesions of a single lobe, so as to solve the problem that the traditional method for judging small airway lesions is based on the entire lung and cannot be judged based on a single lobe, resulting in the inability to judge small airway lesions Distribution problems on specific lobes
