X-ray imaging system for radiation therapy

A radiation system comprising:

• a first rotation portion;
• a second rotation portion;
• a treatment head comprising a first portion configured to emit a treatment beam towards an object and a second portion configured to adjust a radiation range of the treatment beam, the second portion of the treatment head being movable with respect to the first portion of the treatment head, and the first portion of the treatment head being disposed in the first rotation portion;
• one or more imaging sources, at least one of the one or more imaging sources being disposed in the second rotation portion;
• and
• at least one detector, wherein
• the second rotation portion is able to rotate independently from the first rotation portion, the first rotation portion is circular, and the first rotation portion is located outside the second rotating portion in a radial direction of the first rotation portion;
• wherein
• a first component of the first rotation portion and a second component of the second rotation portion are located on a first plane;
• the first component of the first rotation portion includes the first portion of the treatment head;
• and
• the second component of the second rotation portion includes the second portion of the treatment head, the second portion of the treatment head comprising a collimation component configured to adjust the radiation range of the treatment beam.

A system, comprising:

• at least one storage device including a set of instructions;
• at least one processor in communication with the at least one storage device and a radiation system, wherein the radiation system includes:
• a first rotation portion;
• a second rotation portion;
• a treatment head, at least a portion of the treatment head being disposed in the first rotation portion;
• one or more imaging sources, at least one of the one or more imaging sources being disposed in the second rotation portion;
• and
• at least one detector, wherein
• when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
• causing the second rotation portion to rotate independently from the first rotation portion, wherein the first rotation portion is circular, and the first rotation portion is located outside the second rotating portion in a radial direction of the first rotation portion;
• generating an image by causing the at least one of the one or more imaging sources to emit at least one imaging beam toward an object;
• causing a region of the object to be positioned in the radiation system based on the image;
• causing the first rotation portion and the second rotation portion to rotate synchronously;
• and
• causing the treatment head to emit a treatment beam to the region of the object;
• wherein
• a first component of the first rotation portion and a second component of the second rotation portion are located on a first plane;
• and
• the treatment head comprises a first portion and a second portion, wherein
• the first component of the first rotation portion includes the first portion of the treatment head, the first portion of the treatment head being configured to emit the treatment beam towards the object;
• and
• the second component of the second rotation portion includes the second portion of the treatment head, the second portion of the treatment head comprising a collimation component configured to adjust a radiation range of the treatment beam.
