1. A radiation treatment system comprising:
a gantry configured to rotate around an object;
a treatment head moving with the gantry, the treatment head being configured to deliver a treatment beam to the object, the treatment beam providing a maximum treatment radiation region;
a plurality of imaging radiation sources configured to emit imaging beams toward the object; and
one or more first detectors configured to detect at least a portion of the imaging beams,
wherein when the treatment head is delivering the treatment beam to the object, at least one of the plurality of imaging radiation sources is positioned at an edge of the maximum treatment radiation region,
the plurality of imaging radiation sources and the one or more first detectors is operably coupled to or mounted on a ring, and
the ring carrying the plurality of imaging radiation sources and the one or more first detectors is configured to perform an oscillation in a range of 360 degrees or a limited angle range less than 360 degrees.
