Micro-CT was performed to a small bivalve Musculus costulatus. This specimen was fixed and preserved in 96% ethanol. Specimen was stained in 0.3% PTA solution in 70% ethanol for 5 days. Scan was performed with a Skyscan 1172 at a voltage of 59kV and 167μΑ without filter for a full rotation of 360o . This specimen was scanned at the highest camera resolution with an exposure time of 1555ms. This scan was performed for testing contrast enhancing techniques for the application of micro-CT in marine biodiversity studies (http://www.microscopy-analysis.com/sites/default/files/2013_March_Faulwe...). Specimen was provided and scanned by Sarah Faulwetter.
