A geometric system using three rows of pinhole collimator cameras was studied computationally and experimentally in order to investigate a method for measuring the distribution of RI in 3-dimensional space. Experimental comparison of the actual position with the reconstructed result using a Co-57 source confirmed that the position of the source can be reconstructed in three dimensions.
