Abstract
A photomultiplier assembly for use in gamma cameras, for example, includes an array of head-on type photomultipliers disposed in parallel relation to one another. The array of photomultipliers has a plurality of dead spaces, in which reflectors are respectively disposed. The reflector can reflect light which has entered the corresponding dead space to an upper portion of a side wall of aproximate photomultiplier. A side photocathode surface is formed on an inside surface of the upper portion of the side wall of the photomultiplier. Therefore, the light which has entered the dead space is reflected by the reflector and impinges on the side photocathode surface to be converted into photoelectrons.
