microCT dataset of digitized specimen - Neomicrorbis azoricus SMF 32977

A specimen of N. azoricus from the Indian Ocean (SMF 32977) was scanned using a Werth Tomoscope® XS Plus 200 microCT (Giessen, Germany). The specimen had been fixed in formalin and subsequently preserved in 70% ethanol. Before undergoing microCT scanning, it was stained with a 0.3% phosphotungstic acid (PTA) solution in 70% ethanol for contrast enhancement. The scanning parameters were as follows: SMF 32977 was scanned using a voltage of 140 kV, a generator current of 139 µA, and a generator power of 19.5 W. The exposure time was set at 500 ms across a total of 6381 projections, with 3 projections averaged to enhance image quality. This achieved a voxel resolution of 3.56 µm. Surface renderings of the specimens were created using Drishti v3.1 software (Australian National University, Canberra) (Limaye 2012).
