Abstract
The present invention relates to a system and method for using discrete photon counting to produce transmission radiographic images of a target object with improved spatial resolution and high system sensitivity. The system comprises a radiation source for directing photons at a target object and a detector array for receiving photons passing through the target in order to provide an image of the target density. The detector array is configured to enhance spatial resolution and maintain high system sensitivity. To correct the parallax effect that may be induced by such configuration of the detector array, a process can be computer implemented or program coded to parallax correction.
