Figure 5

The profile plot of end-inspiration phase gating and the profile plots that were used to derive the background value of pixels are shown (left panel), and the temporal information derived from TI-EPI portal of end-inspiration phase gating shows right. The 'temporal' information, i.e. frequency of imaging of the block at pixels of the "line trajectory" during end-inspiration TI-EPI acquisition, shows in a ratio (grey value of mobile object/grey value of static object). For this ratio the background grey-value of pixels was derived by subtracting the pixel grey values measured by the "red profile" from those measured by "green profile" (left panel).
