A system according to some embodiments may include a treatment head to emit a megavoltage radiation beam toward a volume, a plurality of X-ray sources to emit a respective kilovoltage radiation beam toward the volume while the plurality of X-ray sources are substantially stationary with respect to the volume, a detector to receive the plurality of kilovoltage radiation beams after having passed through the volume, and a processor to generate a three-dimensional image of the volume based only on the plurality of kilovoltage radiation beams received by the detector while the plurality of X-ray sources were substantially stationary with respect to the volume.
