1. A medical imaging system comprising:
a movable station including a C-arm having a first end and a second end that are movable along an arc relative to the movable station;
a collector attached to the first end of the C-arm;
a first X-ray beam emitter and a second X-ray beam emitter both facing the collector to emit X-ray beams in a direction of the collector and both attached to the second end of the C-arm;
the collector and the first and second X-ray beam emitters are spaced apart relative to each other along a lateral axis orthogonal to the arc; and
a controller configured to obtain at least one set of images by rotating the collector and the first and second X-ray beam emitters along the arc about a scanned volume, and to combine the at least one set of images to generate a three-dimensional image of the scanned volume,
wherein the controller is further configured to activate the first X-ray beam emitter to emit X-rays while maintaining the second X-ray beam emitter deactivated while obtaining a first set of images by rotating the collector and the first and second X-ray beam emitters along the arc about a scanned volume.
