Figure 3.

TI-EPI portals of the phantom imaged in static and moving (gated) mode in both inspiration and expiration. The white arrow on the "End-inspiration (phase gating)" portal points to a pixel location (white dot) of which temporal block information was derived. The lowermost panels shown the merged TI-EPI portals at end-inspiration and end-expiration (bottom left), and the corresponding non-gated image is also shown (bottom right). The bottom left portal shows the profile plot of measured grey values along an 8 cm white line.
