Computed tomography analysis of multicorer IP21_020MUC, core 3

Selected multicorer cores and ROV push cores (IP21_021-17, IP21_021-18, IP21_061, IP21_061-19, IP21_061-20) of R/V Island Pride cruise IP21 were scanned using a Philips Brilliance iCT Elite 256 computer tomograph (CT) at the hospital Klinikum Bremen-Mitte, with an X- ray source voltage of 120 kV and a current of 300 mA. The CT image stacks have a physical resolution of 0.293 mm in the x and y directions and 0.625 mm resolution in the z direction (collimation; 0.3 mm reconstruction interval). Images were reconstructed using the filtered Back Projection (fBP) mode and a bone kernel (YB (Enhanced)). […]

本研究选取了‘岛之骄傲号’（R/V Island Pride）航次IP21所采集的多管岩心（multicorer cores）与遥控无人潜水器（Remote Operated Vehicle, ROV）推送岩心，具体编号为IP21_021-17、IP21_021-18、IP21_061、IP21_061-19、IP21_061-20。上述岩心于不来梅米特医院（Klinikum Bremen-Mitte）使用飞利浦Brilliance iCT Elite 256型计算机断层扫描仪（CT）完成扫描，扫描参数设置为：X射线源电压120 kV，管电流300 mA。该CT图像序列在x、y方向的物理分辨率为0.293 mm，z方向分辨率为0.625 mm（准直参数；重建层间距为0.3 mm）。图像采用滤波反投影（filtered Back Projection, fBP）模式与骨重建核（YB (Enhanced)）进行重建。[...]
