Sample TROND-CT10 was dredged by Wolfgang Berger in September 1980 in Trondheim fjord, Norway (63°36'N, 10°32'E, 50-90\,m water depth) and we are grateful for getting access to the sample through MARUM administration. The specimen was scanned with a Philips Brilliance iCT Elite 256 computer tomograph (x-ray source, voltage: 120 kV; current: 300 mA; physical resolution: 0.212 in xy-direction, respectively, 0.625 mm in z-direction; re-construction interval in z-direction: 0.3 mm; reconstruction: filtered Back Projection (fBP) mode and a bone kernel (YB (Enhanced)). Polyp-cavity (calice) segmentation was perfromed with the ZIB edition of the Amira software (Stalling et al., 2005; http://amira.zib.de) based on the new method describes in Schmitt et al. (submitted).
