Concurrent DC-coupled anode and dynode readout scheme for PET block detectors

摘要

A scintillation detector including one or more photomultiplier tubes, a scintillation block optically attached to the photomultiplier tubes, and a DC-coupled bleeder circuit combining outputs of dynodes of the photomultipliers to provide a DC-coupled dynode output together with a DC-coupled anode output of the photomultiplier tubes. The DC-coupled bleeder circuit includes a RF transformer. A positive high voltage supply also can be used together with a DC-coupled bleeder circuit for the anode outputs.

1. A scintillation detector, comprising:
at least one photomultiplier tube having a plurality of dynodes and an anode; a scintillation block optically coupled to the at least one photomultiplier tube; a DC-coupled anode output; and a bleeder circuit providing a DC-coupled dynode output from at least one of said dynodes, wherein the DC-coupled anode output and the DC-coupled dynode output are obtained simultaneously.
