1. A radiation system comprising:
a gantry;
a treatment head configured to deliver a treatment beam toward an object;
a detector; and
a plurality of imaging sources configured to deliver a plurality of imaging beams toward the object;
wherein the treatment head, the detector, and the plurality of imaging sources are mounted on the gantry;
at least two of the plurality of imaging sources share the detector; and
the detector is configured to detect at least two of the plurality of imaging beams, the detected at least two imaging beams being emitted by different imaging sources of the at least two imaging sources, wherein the detector includes an anti-scatter grid, the anti-scatter grid including a plurality of portions, an orientation of each of the plurality of portions being adjustable to correspond to a direction of at least one imaging beam emitted by at least one DR imaging source included in the plurality of imaging sources.
