Figure 4. This figure demonstrates the effectiveness of the spacer in increasing the distance between the prostate and rectum. (a) Computed tomography
(CT) scan images of original phantom without spacer. (b, c) Implantation of pre-foam (b) and post-foam (c) polycaprolactone (PCL) spacers.
(d) 3D modeled phantom images with an implanted post-foam spacer.

Figure 5. This figure provides detailed insight into the microstructure of the foamed spacer, which is important for understanding cell morphologies.
