Zoom (VOI-04) at 6.51um of the heart of donor S-20-29, 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.

供体S-20-29心脏样本中，6.51μm分辨率下的缩放型感兴趣体积（Volume of Interest, VOI）-04，于欧洲同步辐射装置（European Synchrotron Radiation Facility, ESRF）的BM18光束线，采用分层相衬层析成像（Hierarchical Phase-Contrast Tomography, HiP-CT）技术完成扫描。分层相衬层析成像（HiP-CT）是一种可实现视场与分辨率解耦的X射线成像技术，能够以细胞级（微米级）分辨率对人体任意部位成像。该技术的成像区域既可为25μm分辨率下的完整器官，也可为这些器官内的缩放区域，分辨率可达6μm至0.6μm，其分辨率为医用CT的100倍。
