    Study Notes

    Overview of X-Ray Circuit Components

    • The low-voltage circuit is the subcircuit between the AC power supply and the primary side of the step-up transformer.
    • The control console contains all devices in the low-voltage circuit except the step-up transformer.
    • The incoming voltage is monitored and stabilized by a voltage compensator due to small variations in the incoming line voltage that may cause large variations in the kVp to the x-ray tube.
    • The autotransformer serves three functions: it provides the means for kVp selection, it provides compensation for fluctuations in the incoming line voltage, and it supplies power to other parts of the x-ray circuit.
    • The exposure switch allows electric current to flow through the primary side of the step-up transformer, inducing current flow through the secondary side and creating voltage across the x-ray tube.
    • The exposure timer is a device that terminates the exposure and is set by the operator on the control console.
    • The filament circuit supplies a low current to heat the x-ray tube filament for thermionic emission of electrons.
    • The primary side of the filament circuit begins and ends with the contacts on the autotransformer.
    • The mA selector controls amperage in the filament circuit, determining the number of available electrons at the x-ray tube filament and thus determining the mA in the high-voltage circuit.
    • The high-voltage circuit begins and ends with the secondary side of the step-up transformer and includes the x-ray tube and the rectifier unit.
    • The step-up transformer increases the incoming voltage by the value of the transformer ratio, which is at least 500:1.
    • The primary purpose of the high-voltage circuit is to supply the x-ray tube with voltage high enough to create x-rays, and it is located in a tank near the x-ray machine with oil surrounding the transformers inside the tank for heat dissipation.
