Abstract
A composite crystal array for a pixelated gamma camera and a method of making thereof, which are adapted to a photoelectric matrix that consists of position sensitive photomultiplier elements, in which the photoelectric matrix is divided into sensible and non-sensible areas with a geometric distribution, so as to set a ratio of a segmented region; a configuration detail of a partial optical splitting crystal array and a configuration detail of a whole optical splitting crystal array are set according to the ratio of the segmented region; and the partial optical splitting crystal array and the whole optical splitting crystal array are made according to the two configuration details, and two kinds of crystal arrays are combined to form a whole crystal array for the pixelated cameras according to the segmented region, so that the effective area of the pixelated camera is kept continuous and the resolution thereof is kept uniform.
