Three chronic lung diseases will constitute the target of the study, by using retrospective data from each lung disease:~Cystic fibrosis~Asthma and COPD~Interstitial lung diseases~Dedicated algorithms will be developped for each disease condition.
Lung structural abnormalities are complex, time-consuming, and may lack reproducibility to evaluate visually on CT scans. The study's aim is to perform automated recognition of structural abnormalities in CT scans of patients with chronic lung diseases by using dedicated software.
