An imaging apparatus for x-rays includes a scintillator, overlying an array (100) of imaging pixels on a substrate, and at least one trigger pixel array (20) externally peripheral to the array of imaging pixels on the substrate such that the trigger pixel array is not substantially overshadowed by the scintillator from incident x-ray radiation. A layer substantially impervious to light but transparent to x-rays overlays the trigger pixel array, such that the trigger pixels are unresponsive to light but triggered by direct hits from incident x-ray photons. |
