摘要
A system and method for image-guided radiotherapy are provided. The system may include a treatment assembly and an imaging assembly. The treatment assembly may include a first radiation source configured to deliver a treatment beam. The treatment assembly may have a treatment region relating to an object. The imaging assembly may include a second radiation source and a radiation detector. The second radiation source may be configured to deliver an imaging beam, and the radiation detector may be configured to detect at least a portion of the imaging beam. The imaging assembly may have an imaging region relating to the object. The first radiation source may be rotatable in a first plane, and the second radiation source may be rotatable in a second plane different from the first plane, such that the treatment region and the imaging region at least partially overlap.
