Abstract: A system operable for detecting radiation to scan an object includes scintillators that have respective lengths that are greater than their respective widths and an imager that has a planar array of pixels. The scintillators are coupled to the imager with their respective longitudinal axes parallel to each other. An incoming radiation beam that has passed through the object enters the scintillators through respective surfaces of the scintillators that are transverse to the longitudinal axes, and is converted by the scintillators into light that is received by respective subsets of the planar array of pixels.

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: 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.

Abstract: One facilitates capturing samples as pertain to an object to be imaged by providing N pulsed sampling chains (where N is an integer greater than 1) where these sampling chains are in planes substantially parallel to one another and are substantially equidistant from adjacent others by a given distance. By one approach, the ratio of this given distance to a desired sample interval is approximately an integer that is relatively prime to N. So configured, a complete set of samples of the object can be captured by the sampling chains in a single pass notwithstanding that the object and the sampling chains are moving quickly with respect to one another.

Abstract: At least three radiation-detection views are used to facilitate identifying material as comprises an object being assessed along a beam path relative to that object. This comprises developing a first radiation-detection view (101) as corresponds to the material along the beam path, a second radiation-detection view (102) as corresponds to the material along substantially the beam path, and at least a third radiation-detection view (103) as corresponds to the material along substantially the beam path. At least one of the source spectra and detector spectral responses used for these radiation-detection views are different from one another for each view. One then uses (104) these radiation-detection views to identify the material by, at least in part, differentiating the material from other possible materials.

Abstract: A detector array is disposed relative to a radiation source such that radiation from the radiation source over a predetermined time period is substantially similar across the detector array. The detector array includes radiation detectors operatively coupled to detector electronics. The radiation filter material is disposed at least partially between the radiation source and the detector array such that different portions of the detector array are exposed to radiation from the radiation source through either different radiation filter material thicknesses or different radiation filter material compositions during the predetermined time period. So configured, information regarding the radiation such as beam quality information for radiation pulses is collected and used to confirm the quality of the radiation source or to adjust data collected by the radiation system.
