Three new coded aperture mask designs are proposed. These masks enjoy many of the valuable properties possessed by uniformly redundant arrays and in addition have simple geometric design and few restrictions on size. Decoding arrays for the new designs are given, and an analysis of their noise characteristics is included. Two of the new mask designs are compared with a URA mask when used for imaging phantoms using a conventional hospital gamma camera.
