The present disclosure may provide a radiation system including a first rotation portion, a second rotation portion, a treatment head, one or more imaging sources, and at least one detector. At least a portion of the treatment head may be disposed in the first rotation portion. At least one of the one or more imaging sources may be disposed in the second rotation portion. The second rotation portion may be able to rotate independently from the first rotation portion.

X-ray imaging system for radiation therapy

The present disclosure may provide a radiation system. The radiation system may include a treatment head, a detector, a plurality of imaging sources, and a gantry. The treatment head, the detector, and the plurality of imaging sources may be mounted on the gantry. The treatment head may be configured to deliver a treatment beam toward an object. The plurality of imaging sources may be configured to deliver a plurality of imaging beams toward the object. At least two of the plurality of imaging sources may share the detector. The detector may be configured to detect at least two of the plurality of imaging beams. The detected at least two imaging beams may be emitted by different imaging sources of the at least two imaging sources.

Systems and methods for four-dimensional CT scan are provided. The methods may include determining a first region of a subject and a second region. A movement of the subject may occur within the second region. The methods may further include generating a first image set by performing, based on a first operation parameter corresponding to a first scan, the first scan on the first region of the subject, and generating a second image set by performing, based on a second operation parameter corresponding to a second scan, the second scan on a second region of the subject. The methods may further include obtaining movement information corresponding to the movement of the subject and determining a final image set based on the first image set, the movement information, and the second image set.

Systems and methods for four-dimensional CT scan

The present disclosure is related to systems and methods for radiation. The method may include obtaining a plurality of reference images of a target of a subject and reference physiological motion information of the subject. The plurality of reference images and the reference physiological motion information may be acquired in a radiation period. The method may include establishing a correlation model based on the plurality of reference images and the reference physiological motion information. The method may include monitoring real-time motion information of the target based on the correlation model during a radiation operation performed during the radiation period.
