The image is showing a 3D printed non-drying hydrogel (polyacrylamide, water and glycerol) heart model. This is a prototype measuring approximately 3.5x2.5x2.5 cm to check the integrity of right and left ventricles of the heart. Eventually, a larger model will be printed and be used as suture practice platform for surgeons. The 3D rendered image pseudocolored purple using Isosurface module from Xray CT data having 24-micron voxel size. The sample was scanned using the X5000 NSI High Resolution MicroCT and rendered in 3D using Imaris 3D visualization program at the Carl R. Woese Institute for Genomic Biology Core Facility.
