ABSTRACT:
A three dimensional positron emission tomography system is used in conjunction with a short lifetime positron emitter introduced into a test object to function as a tracer. A plurality of high density, high atomic number scintillating crystals are positioned within a cylindrical volume surrounding the test object, each such crystal being adapted to emit visible light in response to absorption of a gamma ray photon emitted when a positron from the tracer annihilates with an electron within the test object. A plurality of visible light photon counters is provided, with each such counter associated with one of the scintillating crystals such that the emission of visible light from the crystal is detected by the counter. Electronic circuitry sequentially polls the plurality of counters and compiles data indicative of the time at which a visible light photon was detected by each photon counter. A data analyzing system determines, from the time data and the spatial position of each crystal, the time at which and the location within the test subject from which each gamma ray photon originated.
