Figure 6
Examples of 4D extensions to the static 3D foam phantoms. In each case, an early time-point is shown on the left, and a later time-point is shown on the right. Given are an example of a moving phantom, in which the foam moves vertically, an expanding phantom, in which the voids grow in size, and an infiltration phantom, in which the voids fill with a different material over time. |
