X-ray CT images of IODP Hole 386-M0083F@en

Collection of X-ray Computed Tomography (CT) images from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. This was followed by an onshore phase onboard D/V Chikyu between 2022-02-14 – 2022-03-15. X-ray CT scanning was performed on whole-round sections on board D/V Chikyu in July 2021, after the offshore phase and prior to the onshore phase, using a Discovery CT 750HD (GE Medical Systems) that produces 32 0.625 mm thick slice images every 0.4 s. Data generated for each core consist of core-axis-normal planes of X-ray attenuation values that are 512 × 512 pixels in size. Data were stored on the server as DICOM formatted files. The DICOM files were restructured to create 3-D images for further investigation. For publication purposes JPG files of each scanned section were produced imaging the plane representative of the split core surface. […]本数据集包含来自国际大洋发现计划（International Ocean Discovery Program, IODP）386次科考航次（日本海沟古地震学研究）指定钻孔的X射线计算机断层扫描（X-ray Computed Tomography, CT）图像集。该航次的近海作业阶段于2021年4月13日至2021年6月1日期间开展，作业船为日本R/V Kaimei研究船，往返航线始于并终于日本横须贺港。随后的陆上作业阶段于2022年2月14日至2022年3月15日在D/V Chikyu钻探船上完成。X射线CT扫描于近海作业结束后、陆上作业开始前的2021年7月在D/V Chikyu钻探船上开展，使用GE医疗系统的Discovery CT 750HD扫描仪，该设备可每0.4秒生成32张厚度为0.625毫米的断层切片图像。每个岩芯对应的数据集包含垂直于岩芯轴的X射线衰减值平面图像，单张图像分辨率为512×512像素。数据以数字成像与通信医学（Digital Imaging and Communications in Medicine, DICOM）格式文件存储于服务器中。后续将DICOM文件重构为三维图像以开展进一步研究。为满足出版需求，还针对每个扫描岩芯段生成了对应劈开岩芯表面成像的JPG格式图像。[…]
