Abstract
A dual mode radiation detector includes an x-ray detector layer configured to convert incident x-ray radiation into x-ray electrical data, where the x-ray detector forms an incident face of the dual mode radiation detector. The dual mode radiation detector further includes a collimator disposed below the x-ray detector layer, and a gamma photon detector layer disposed below the collimator to convert incident gamma photons into gamma photon electrical data.
