Dynamic chest radiograph interpretation. Visualisation of a dynamic chest radiograph for the purpose of (a) identification of phase of breathing via average pixel density change over time and associated projected lung area (PLA) measurements, (b) Automated hemidiaphragm midpoint tracking. c Shows example images of lung area identification (top) and hemidiaphragm tracking (bottom) in a person with cystic fibrosis bronchiectasis. PLA projected lung area, PLAinsp PLA at full inspiration, PLAexp PLA at maximum expiration, PLAti PLA at point of tidal breath in, PLAte PLA at point of tidal breath out
