Non-destructive elemental analysis method has been developed for the materials by high-energy muon-characteristic X-rays measurement. To further improve the method, we have also utilized two-dimensional cadmium telluride hard X-ray detectors (CdTe-DSDs) for the muonic X-rays measurement to obtain the 3D elemental distribution of the sample. In this work, a 3D imaging system has been created using four CdTe-DSDs. The experiment of 3D elemental imaging for archaeological materials was performed using a negative muon beam at J-PARC/MUSE, and the three-dimensional distribution of silicon and oxygen was confirmed. This presentation introduces the research progress so far.
