Megavolt and kilovolt X-ray imaging from opposite sides of a detector

A radiation detector comprising:

• a housing having a first surface and a second surface;
• a scintillator disposed within the housing and configured to convert incident radiation at a first energy range and the incident radiation at a second energy range into converted optical photons;
• a photosensor array optically interfaced with the scintillator and configured to receive the optical photons from the scintillator;
• and
• a first converter configured to interact with the incident radiation generated at the first energy range;
• wherein incident radiation generated at a first energy range is received through the first surface, incident radiation generated at a second energy range is received through the second surface, the first energy range is different than the second energy range, and the photosensor array receives the optical photons from the scintillator in a same direction for both the first energy range and the second energy range.

A radiation detector for detecting incident radiation in a megavolt voltage range from one side and incident radiation in a kilovolt voltage range from another side, the radiation detector comprising:

• a housing having a first surface and a second surface;
• a scintillator disposed within the housing and configured to convert the incident radiation at the megavolt voltage range and the incident radiation at the kilovolt voltage range into converted optical photons;
• a photosensor array optically interfaced with the scintillator and configured to receive the optical photons from the scintillator;
• and
• a first converter configured to interact with the incident radiation generated at the megavolt voltage range;
• wherein incident radiation generated at the kilovolt voltage range is received through the first surface, incident radiation generated at the megavolt voltage range is received through the second surface, and the photosensor array receives the optical photons from the scintillator in a same direction for both the megavolt voltage range and the kilovolt voltage range.
