Abstract: Some embodiments include a method, comprising: providing a semiconductor substrate including photodetectors on a first side of the substrate; attaching at least one semiconductor device to the first side of the semiconductor substrate; attaching a back support plate to the semiconductor substrate over the at least one semiconductor device; and thinning the semiconductor substrate.

Abstract: In one embodiment, a radiation detector may include a housing, a scintillator, a photosensor array, and a first converter. The housing may include a first image cover associated with a first surface configured to receive incident radiation generated at a first voltage range, and a second image cover associated with a second surface configured to receive incident radiation generated at a second voltage range. The first voltage range may be different than the second voltage range. The scintillator may be disposed within the housing to convert the incident radiation at the first voltage range or the incident radiation at the second voltage range into converted optical photons. The photosensor array may be optically interfaced with the scintillator to receive the optical photons from the scintillator. The first converter may be configured to interact with the incident radiation generated at the first voltage range.

Abstract: Embodiments include a detector with a flexible scintillator screen and a flexible photosensor array and an apparatus with supports coupled to the ends of the detector. The apparatus enables the detector to either flex repeatedly or be flexed and then fixedly held in a flexed configuration.

Abstract: Methods and systems for scanning objects comprising scanning a portion of an object by a first radiation beam having a first value of a beam characteristic, such as the dose, and detecting the first radiation beam after interaction with the object by a first detector. It is determined whether to change the first value to a second value based, at least in part, on the detected first radiation beam. That portion of the object is then scanned by a second radiation beam having the first value or the second value based on the determination. The second radiation is detected after interacting with the object by a second detector. The second detector may have a second resolution greater than a first resolution of the first detector. The first and second radiation beams may be formed by first and second slots angled with respect to each other.
