3d backscatter imaging system

摘要

Systems and methods for imaging an object using backscattered radiation are described. The imaging system comprises a radiation source for irradiating an object, the radiation source rotationally movable about the object. The imaging system also contains a detector for detecting backscattered radiation from the object. The detector can be disposed on substantially the same side of the object as the source and the detector can be rotationally movable about the object. The detector can be separated into multiple detector segments (i.e., using a collimator grid) so that each segment has a single line of sight projection through the object and so only detects radiation along that line of sight. The restricted line of sight allows each detector segment to isolate the desired component of the backscattered radiation. The radiation source and the detector can move independently of each other about the object, collecting multiple images of the object at different angles of rotation. These multiple images can be used to generate a three dimensional reconstruction of the object. Other embodiments are described.
