title: Zoom (ROI-05) at 6.54um of the brain of donor LADAF-2021-17, scanned at ESRF on beamline BM18.

description: Zoom (ROI-05) at 6.54um 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.
