Abstract:
A computerized tomography system comprising:an x-ray source and a detector each disposed to pass x-rays through a test object toward the detector, wherein the detector provides a detected image signal of the intensity of the x-rays received thereby, at each of several positions along a predefined path;a transmitter disposed to encode the detected image signal with a carrier signal to provide a modulated data signal; anda receiver coupled to the transmitter and including an automatic radio frequency (RF) attenuation loop, the automatic RF attenuation loop configured to receive a coupled modulated data signal potentially having a wide range of power levels and to digitize and demodulate the coupled modulated data signal, wherein an amplitude associated with the coupled modulated data signal is selectively configured in response to a previous coupled modulated data signal via a feedback loop included in the automatic RF atenuation loop.
