Radiography by selective detection of scatter field velocity components
First Claim
1. A reconfigurable collimated radiation detector, comprising:
- at least one collimated radiation detector, said detector having an adjustable collimator including at least one feature optically coupled thereto, wherein adjustments to said adjustable collimator selects particular directions of travel of scattered radiation emitted from an irradiated object which reach said detector.

Abstract
A reconfigurable collimated radiation detector, system and related method includes at least one collimated radiation detector. The detector has an adjustable collimator assembly including at least one feature, such as a fin, optically coupled thereto. Adjustments to the adjustable collimator selects particular directions of travel of scattered radiation emitted from an irradiated object which reach the detector. The collimated detector is preferably a collimated detector array, where the collimators are independently adjustable. The independent motion capability provides the capability to focus the image by selection of the desired scatter field components. When an array of reconfigurable collimated detectors is provided, separate image data can be obtained from each of the detectors and the respective images cross-correlated and combined to form an enhanced image.
