This work is based on experiments performed at the Swiss spallation neutron source SINQ, Paul Scherrer Institute, Villigen, Switzerland.

X-ray (xray_data.tiff) and neutron microscopy (neutron_data.tiff) of the same piece of human cortical bone. Neutron data were collected at the neutron microscope at SINQ, PSI, Switzerland while the x-ray data were collected in house at an VERSA 620 X-ray microscope. The voxel size is in both case 2.7 µm
