Abstract
An arrangement for counting detectable events, such as scintillation events in a specimen sample utilizes first and second detector elements arranged on either side of the sample. The first detector is of the type which is able to produce information relative to the position of the event in the sample. The second detector generates a timing signal responsive to the detected event. In certain embodiments, the first detector also issues a timing signal in response to the detection of the event, and both timing signals are compared for temporal coincidence, whereupon circuitry for determining the position of the detectable event is triggered. The total energy of the event can be obtained from addition of the analog amplitudes of the timing signals. In certain embodiments, the second detector also produces position information, and the first and second detectors may provide respective coordinate values of a coordinate pair.
