1. A system for producing diagnostic images comprising:

  • a clock generating a clock signal;

    a radiation source directing photons through a subject to be imaged;

    a detector system detecting the photons;

    a memory module recording a time of detection of the photons by the detector system with respect to the clock signal; and

    a processor calculating a time of flight (TOF) of the photons to the detector system and comparing the TOF to a reference TOF to determine a delay in the TOF attributable to the photons passing trough the subject.
