(Upper left) Configuration of the multi-angle measurement. (upper right) Energy spectrum obtained via a HCC by using Cs-137, Na-22, and Am-241 sources simultaneously. (lower) Slice of the 3D reconstructed image (right) and the projections of each source (left); green, red, and blue conversions correspond to Cs-137 (662 keV; Compton mode), Na-22 (PET mode), and Am-241 (60 keV; pinhole mode) sources, respectively.
