Zoom (ROI-11) at 6.36um of the brain of donor LADAF-2021-17, scanned at ESRF on beamline BM18.

Zoom (ROI-11) at 6.36um of the brain of donor LADAF-2021-17, scanned at ESRF on beamline BM18 using the HiP-CT imaging technique. Hierarchical Phase-Contrast Tomography (HiP-CT) is an X-ray technique that decouples field of view and resolution to image anywhere in the human body with cellular (micron) resolution. Imaging areas can be full organs at a resolution of 25 micron or zoomed regions in these organs with resolutions between 6 and 0.6 micron, one hundred times the resolution of medical CT.

本数据集为供体LADAF-2021-17的大脑样本在6.36微米分辨率下、编号为ROI-11的感兴趣区域（Region of Interest）的放大成像结果，该成像于欧洲同步辐射光源（European Synchrotron Radiation Facility, ESRF）的BM18光束线完成，采用分层相衬层析成像（Hierarchical Phase-Contrast Tomography, HiP-CT）技术。分层相衬层析成像（HiP-CT）是一种X射线成像技术，可通过分离视场与分辨率参数，实现人体任意部位的细胞级（微米级）分辨率成像。该技术的成像范围既可以是25微米分辨率的完整器官，也可以是上述器官内的放大区域，分辨率覆盖6至0.6微米，其成像分辨率可达医用CT的100倍。
