1. An apparatus comprising:
a first radiation source configured to produce a first divergent radiation beam toward an object;
a second radiation source configured to produce a second divergent radiation beam toward the object; and
an image sensor;
wherein the object is configured to rotate with respect to the image sensor, the first radiation source, and the second radiation source,
wherein relative positions among the image sensor, the first radiation source, and the second radiation source are fixed;
wherein the image sensor comprises a plurality of radiation detectors spaced apart from one another;
wherein the image sensor is configured to capture, by using the radiation detectors and with the first divergent radiation beam, an image of a first portion of the object, and is configured to capture, by using the radiation detectors and with the second divergent radiation beam, an image of a second portion of the object; and
wherein the image sensor is configured to form an image of the object by stitching the image of the first portion and the image of the second portion.
