ABSTRACT:
An image sensor and a method for using the same to capture an x-ray image are disclosed. The image sensor includes an output bus, a two dimensional array of pixel sensors that receives light from a layer of scintillation material and a controller. Each pixel sensor includes a capacitor, a plurality of light sensors, a charge converter and a transfer gate. Each of the light sensors includes a photodiode and a photodiode transfer gate that connects the photodiode to the capacitor. During readout, the charge on selected ones of the photodiodes is transferred to the capacitor. The charge on the capacitor is converted to a signal that is coupled to the output bus through the transfer gate by the controller. The number of photodiodes that are connected to the capacitor during the readout can be controlled to assure that the charge converter does not saturate.
