▼a Projection x-ray imaging is commonly employed to visualize internal human anatomy and used to produce diagnostic images. Modern projection imaging is typically performed using an active matrix, flat panel imager that is comprised of a converter |

▼a Recently, imagers employing a second method for creating x-ray images -- referred to as photon counting -- have been developed and used to perform mammographic imaging (a form of projection imaging). Photon counting involves measuring the energy |

▼a Current photon counting mammographic imagers are based on crystalline silicon and are limited in detection area. In order to produce an image, the array is moved in a scanning motion across the object of interest. A photon counting imager with l |

▼a Using poly-Si, a set of prototype arrays have been designed and fabricated. The design of the arrays consists of four components: an amplifier, a comparator, a clock generator, and a counter. Several circuit variations were created for each comp |
