1. A cone-beam computer tomography imaging method comprising:
acquiring a plurality of sets of projection images of a target volume by irradiating the target with radiation from an X-ray source,
each set of projection images being associated with:
a plurality of locations of the X-ray source along a respective one of a plurality of scanning arc segments, the plurality of locations of the X-raw source being obtained by rotating the X-ray source around a rotation axis, and
a respective one of a plurality of locations of the treatment couch along one or more planes that are orthogonal to the rotation axis of the X-rays source, the plurality of locations of the treatment couch being obtained by moving the treatment couch around the one or more planes; and
generating a three-dimensional image of the volume based on the plurality of sets of projection images.
