Tomography images obtained before and after treatment of nail B. There is no significant difference in the X-ray images (a and b), but some \(\approx 100\) \(\mu m\) wide bright band can be seen close to the core of the nail on the neutron images before the treatment (c), which disappear after treatment (d). Arrows indicate zones of interest. a X-ray tomography: before treatment, b X-ray tomography: after treatment, c Neutron tomography: before treatment, d Neutron tomography: after treatment
