Some embodiments include a system, comprising a hybrid imaging device comprising: a first scintillator; a first detector sensors configured to generate a signal based on photons emitted from the first scintillator; a second scintillator; a second detector sensors configured to generate a signal based on photons emitted from the second scintillator; and a control logic coupled to the first detector layer and the second detector layer; wherein: a material of the first scintillator is different from a material of the second scintillator; the first detector overlaps the second detector; and the control logic is configured to generate dose data in response to the first detector and image data in response to the second detector.

Hybrid dosimetry and imaging system

An imaging apparatus includes a first X-ray detector that includes: a low energy scintillator operable to convert an incident X-ray spectrum into a first set of light photons; a first light imaging sensor operable to generate a set of low energy image signals from the first set of light photons, wherein a first exit radiation is a remainder portion of the first incident radiation after the X-ray spectrum passes through the low energy scintillator and the first light imaging sensor; an energy-separation filter operable to absorb or reflect at least a portion of the energy of the first exit X-ray spectrum and convert the first exit X-ray spectrum into a second exit X-ray spectrum; a second X-ray detector that includes: a high energy scintillator operable to convert the second exit X-ray spectrum into a second set of light photons; a second light imaging sensor operable to generate a set of high energy image signals from the second set of light photons; and a processor configured to: generate a high-energy image that is based on the set of high energy image signals and a low-energy image that is based on the set of low energy image signals; and perform a comparison of the high-energy image from the low-energy image to generate a soft tissue image.
