Abstract:
A positron emission detection scanner, comprising:a first plurality of detecting elements arranged in a first two dimensional geometrical array, said detecting elements defining a first detection surface oriented for receiving radiant energy stimulus incident thereto, each of said detecting elements having a second surface for communicating light from a scintillation event occurring within each of said detector elements in response to receiving a radiant energy stimulus; a light transmitting member for receiving the light from each of said detecting elements; and a second plurality of light sensing members arranged in a second two dimensional geometrical array, different from the first geometrical array the light sensing members of the second geometrical array being unaligned with the detecting elements of the first geometrical array, a predetermined group of said plurality of light sensing members being responsive to light in said light transmitting member, the group of light sensing members collecting the light from said light transmitting member, and each one of the light sensing members of said group producing signals proportional to its respective portion of the collected light.
