X-Ray tube voltage indicator

摘要

An X-ray generator system having control circuitry disposed for applying a selected voltage between cathode and anode electrodes of an X-ray tube and for sending a selected current through the tube during an X-ray exposure, the control circuitry including a voltage indicator network disposed for subtracting from the selected voltage anticipated losses in accordance with the level of selected current to indicate prior to the initiation of the X-ray exposure the actual voltage that will be applied between the cathode and anode electrode during the X-ray exposure.
