Examples of respiratory patterns in the RV signal from three separate studies. (a) Respiratory patterns generated by deliberately varying tidal volume cyclically. The ROI is fitted to the chest region using a flood fill technique. (b) Respiratory patterns manifest in a signal collected during a breathe-down study. The ROI is a rectangular subset of the chest. (Reprinted from [17].) (c) A simulated apnea signal. The ROI is the whole image.
