Figure 1
Two examples of X-ray computed tomography images of foam samples (left, middle), and an example of a computer-generated phantom from the proposed foam phantom family (right). In all three images, a cropped region of the entire sample is shown. A graphite foam sample (Evans et al., 2019; Evans, 2019) is shown on the left, and a liquid foam sample (Raufaste et al., 2015), available at Tomobank (De Carlo et al., 2018), is shown in the middle. |
