Abstract
A method and apparatus is provided to detect and correct for distributed X-ray detection events in which the electrical signal arising from the detection of an X-ray is distributed across more than one element of an X-ray detection array. Examples of distributed-detection events include charge sharing across adjacent boundaries between detector elements and X-ray fluorescence between detector elements. Distributed-detection events can be determined by their corresponding to a partial-detection energy that is in a range of energies great than an upper energy for noise and cross-talk and less than a lower energy for an X-ray spectrum from an X-ray source. For a distributed-detection event, the energy of the event is recorded using a sum of electrical signals from the detector elements of the event.
