1. A method comprising:
aligning a collimator and a plurality of radiation detectors of an image sensor by:
moving the radiation detectors along a first direction;
moving the collimator along a second direction perpendicular to the first direction;
rotating the collimator about an axis perpendicular to the first direction and the second direction;
wherein the plurality of radiation detectors are configured to capture images of portions of a scene at different image capturing positions, respectively, and to form an image of the scene by stitching the images of the portions.
