PURPOSE:To eliminate the change in time aging for tube current, by keeping the tube current of X-ray tube, through the provision of the DC bias block circuit at the secondary coil of the filament transformer to which the filament of the X-ray tube is connected. CONSTITUTION:The DC bias ...
TUBE CURRENT TIME PRODUCT CONTROL DEVICE OF X-RAY
In an exemplary embodiment in order to establish the desired relationship between x-ray tube voltage and x-ray tube current, at least one series resistance is connected in the power path between the mains and the x-ray tube. A switching device for by-passing the series resistance is present...
Current flowing in X-ray tube =1m A Potential difference =25 kV Current (I) is given by I="ne" where, n =number of electrons hitting the target per second. :. " "n=(I)/(e)=(1xx10^(-3))/(1.6xx10^(-6))=6.25xx10^(15) Now, the energy falling on t
