Patent ID: 11882378

Abstract:
Disclosed herein is a method, comprising sending radiation beam groups (i, j), i=1, . . . , M and j=1, . . . , Ni toward a same scene, wherein each radiation beam group comprises multiple parallel fan radiation beams sent simultaneously, wherein for each value of i, the radiation beam groups (i, j), j=1, . . . , Ni are parallel to each other and are sent one group at a time, and wherein no two radiation particle paths of two respective radiation beam groups with 2 different values of i are parallel to each other; for i=1, . . . , M and j=1, . . . , Ni, capturing with radiation of the radiation beam group (i, j) a partial image (i, j) of the scene; for each value of i, stitching the partial images (i, j), j=1, . . . , Ni; and reconstructing a 3-dimensional image of the scene from the stitched images (i), i=1, . . . , M.
