ABSTRACT:
An imaging system that removes an electrical charge from a sensor. The system includes a generator that generates x-rays, a sensor that stores an electrical charge, a plate positioned above the sensor and a light source. A controller determines whether the electrical charge should be removed from the sensor. If it is determined that the electrical charge should be removed, the controller controls the light source to illuminate the plate to distribute the light on a top surface of the sensor. A method includes arranging a plate above the sensor and a light source next to the plate, generating x-rays towards the sensor, and storing an electrical charge in the sensor. If it is determined that the electrical charge should be removed, the light source is controlled to illuminate the plate so that the light from the light source is distributed on a top surface of the sensor.
