We report the results of experiments for reconstructing three-dimensional volume data of distributions of radiation sources via two reconstruction algorithms from measurement datasets by a Compton camera. To obtain accurate distributions of radiation sources, which were released by the Fukushima Daiichi Nuclear Power Plant accident, detailed measurements of $$gamma$$ rays are necessary. In this report, as a preliminary experiment, we address three-dimensional reconstruction from measurement data under ideal conditions, using two algorithms: a three-dimensional back-projection method and a list-mode maximum likelihood estimation method. By using these methods, the radiation sources can be accurately reconstructed from the measurement datasets.
