A system and method for detection of x-rays is provided. An x-ray detector system may include an energy-integrating x-ray detector having an array of x-ray sensing elements that are configured to sense x-rays emitted from an x-ray source and generate energy-integrating x-ray data. The system may also include a photon-counting detector having another array of x-ray sensing elements configured to determine an interaction between individual x-ray photons with individual sensing elements of the another array of x-ray sensing elements to generate photon-counting x-ray data. The system may further include electronics configured to receive the energy-integrating x-ray data and the photon-counting x-ray data simultaneously.
