The collection comprises the ZooMS dataset, 3 OBJ files for use with 3D viewer software, and 774 CT scan images in JPEG format that contain 3 separate slices or views (Front, Right and Top).
The CT scan was undertaken using a Nikon XT H 225 micro-scanner with a transmission target. Attempts to keep the dosage as low as possible were made in order to avoid any damage to the sample, so the scan was run at 70kv and 80μA. In total 1,448 projects were taken at two frames per projection, with an exposure set at 100ms and magnification at x7.2. CT data was reconstructed using CT Pro 3D software, and processed with VG Studio Max 2.1 software.
