Background Total lung capacity (TLC) has been estimated with use of chest radiographs
based on time-consuming methods, such as planimetric techniques and manual …

Computed tomography (CT) imaging is being increasingly used in clinical practice for
detailed characterization of lung diseases. Respiratory diseases involve various …

Quantitative computed tomography (QCT) has recently gained an important role in the
