Disclosed is an arm frame structure for a radiation imaging system, comprising a first upright column, a mounting frame, and first and second collimators mounted on said first upright column, and first and second detector devices. A mounting member, is attachable to an end of one or more of the rods, so as to project beyond the post. Furthermore, the distance between the center axis of the outer circumference of the outermost nozzle and each of center axes of inner circumferences and outer circumferences of the inner nozzles is not more than 0. Fourier transformation is performed on the data constellation to obtain a transformed data constellation. An element table including at least one cell pointer for each page element is generated. Since the substrate dividing work after block molding is performed by dicing while vacuum-chucking the surface of the block sealing member, the substrate division can be done without imposing any stress on an external terminal mounting surface of the matrix substrate.
