The advantages of a laser-driven proton acceleration have prompted studies of laser-induced protonradiography. As the CR-39 solid-state nuclear-track detector is suitable for measuring chargedparticles and can be used in proton radiography, we studied laser-induced proton radiography withthe CR-39 for several years, and we were able to obtain a spatial resolution of about 10 μm. For obtaining an image with a spatial resolution of a few μm, we investigated the effect of theCR-39 etching conditions on the spatial resolution and carried out imaging experiments using finephantoms. Experiments were performed using the 100-TW titanium-sapphire laser system at theAdvanced Photonics Research Institute of the Gwangju Institute of Science Technology. We havedemonstrated that images with a spatial resolution of about several μm can be achieved usinglaser-induced proton radiography.
