Abstract: Disclosed herein is a method, comprising: capturing portion images of scene portions (i), i=1, . . . , N of a scene with radiation detectors of an image sensor. For i=1, . . . , N, Qi portion images of the scene portion (i) are respectively captured by Qi radiation detectors of the P radiation detectors, Qi being an integer greater than 1. The Qi portion images are of the portion images. The method further includes, for i=1, . . . , N, generating an enhanced portion image (i) from the Qi portion images of the scene portion (i). Generating the enhanced portion image (i) is based on positions and orientations of the Qi radiation detectors with respect to the image sensor and displacements between Qi imaging positions of the scene with respect to the image sensor. The scene is at the Qi imaging positions when the Qi radiation detectors respectively capture the Qi portion images.

Abstract: Disclosed herein is a method, comprising: causing emission of characteristic X-rays of a chemical element in an object by directing radiation to the object; capturing images of the object using the radiation that has transmitted through the object; capturing images of the chemical element in the object using the characteristic X-rays; reconstructing a three-dimensional image of the object based on the images of the object; determining a three-dimensional distribution of the chemical element in the object based on the images of the chemical element; and superposing the three-dimensional image of the object and the three-dimensional distribution of the chemical element in the object to form a superposed image of the object. The radiation directed to the object comes from multiple radiation sources. The images are captured with multiple image sensors. The radiation sources and the image sensors are stationary with respect to the object.

Abstract: Disclosed herein is an image sensor with two radiation detectors, each having a planar surface for receiving radiation; and a calibration pattern. The planar surfaces of the radiation detectors are not coplanar. The image sensor can capture images of two portions of the calibration pattern, respectively using the radiation detectors. The image sensor can determine two transformations for the radiation detectors based on the images of the portions of the calibration pattern, respectively. The image sensor can capture images of two portions of a scene, respectively using the radiation detectors, determine projections of the images of the portions of the scene onto an image plane using the transformations, respectively, and form an image of the scene by stitching the projections.
