Effects of lung injury on regional aeration and expiratory time constants: insights from four-dimensional computed tomography image registration
Rationale: Intratidal changes in regional lung aeration, as assessed with dynamic four-
dimensional computed tomography (CT; 4DCT), may indicate the processes of recruitment …
