Abstract
An electronic imaging sensor, which has an improved immunity to noise caused by unwanted x-rays, images an object by collecting charge carriers produced in the sensor when the object is exposed to x-rays. One or more shielding areas are formed proximate the sensor to capture or sweep away any undesirable charge carriers generated by the unwanted x-rays. The shielding areas extend deeper beneath the surface of the sensor than the depth at which the desired charge carriers corresponding to the object being imaged is collected. The shielding areas capture charge carriers formed by the unwanted x-rays, which penetrate into the sensor to a greater depth than the depth at which the. desired charge carriers are collected. In this way, the undesirable charge carriers are captured near the region where they are generated and before they migrate towards the surface where they can be collected and manifest as noise in the resulting image of the object.
