Abstract
A timer circuit for an X-ray imaging system having an X-ray generator used to generate images of a patient. The circuit includes a current sensor connected between a main power system and a circuit interrupter, wherein the circuit interrupter is also connected to the X-ray generator. The circuit also includes a timing device coupled between the current sensor and a control computer. The timing device is triggered when a current level detected by the current sensor exceeds an idle current level wherein X-rays are not generated by the X-ray generator. The timing device then measures a time period that the idle current level is exceeded. When the measured time period exceeds a predetermined time period by 10%, the circuit interrupter is activated to turn off current flow to the X-ray generator.
