Abstract:
A photon emission tomography (PET) scanner comprising:a series of spatially separated detectors detecting photon emissions at points about a ring shaped gantry; detector modules collecting signals from the detectors and presenting a series of first terminals providing multiple asynchronous event signals referenced to at least one signal return terminal; at least one earth ground separate from the signal return terminal; detector signal processing circuitry including a series of second terminals providing multiple signal terminals and at least one signal return terminal; a plurality of cables connecting the detector modules to the detector signal processing circuitry, each cable including: (i) a series of mutually insulated and parallel electrical conductors joined edgewise to form a flexible ribbon with the conductors attached to the terminals so that conductors carrying signal return signals alternate with conductors carrying signals; (ii) a first conforming flexible electrical shield covering the ribbon and attached to a signal return terminal; (iii) an insulating layer covering the outside of the first conforming flexible electrical shield; and (iv) a second conforming flexible electrical shield covering the insulating layer attached to the earth ground.
