The coral colony fragment was scanned by a Toshiba Aquilion 64 computer tomograph (CT) at the hospital Klinikum Bremen-Mitte with an x-ray source voltage of 120 kV and a current of 600 mA. The CT image stack has a resolution of 0.35 mm in x-direction and y-direction and 0.5 mm resolution in z-direction (0.3 mm reconstruction unit). Images were reconstructed using Toshiba's patented helical cone beam reconstruction technique (TCOT) and are provided in DICOM-format.

This dataset contains the CT raw data (GeoB12747-1_RawData), the polyp-cavity instance segmentation (GeoB12747-1_cavities) and calices segmentation (GeoB12747-1_calices; given as unique label values) of the polyp-cavity instance segmentation.9.379363.6076Federal Ministry of Education and Researchhttps://doi.org/10.13039/50110000234703F0655ABiological Impacts of Ocean Acidification / BIOACID IIGerman Research Foundationhttps://doi.org/10.13039/501100001659Ba5042/6-1; Ti706/6-1; project 490665120CTcoral – CyberTaxonomische Klassifizierung und morphologische Charakterisierung von Kaltwasserkorallen
