Abstract:
Analysis of the sensitivity of output parameters of X-ray television system of indirect transformation: signal/noise ratio, output signal and quantum detection efficiency to the change of input parameters was performed, using the mathematical model of such a system. The influence of instability of power supply to X-ray tube on output calculation result was analyzed. The group of input parameters of the model was determined, the uncertainty of which has the strongest effect on output signal of X-ray television system. 10 Ref., 2 Tabl., 2 Fig.
Keywords: digital radiography, X-ray television system, X-ray screen, signal/noise ratio, quantum detection efficiency, model parameters, parameter uncertainty
