Description

Technical Field

[0001] The utility model relates to the technical field of tumor radiation, in particular to a positioning device for precise radiotherapy of body tumors. Background Art

[0002] Image-guided radiotherapy is characterized by the Halcyon radiotherapy system's introduction of a KV-CBCT scanning imaging system and high-quality iCBCT image reconstruction mode, which can provide diagnostic CT-level high-definition images. Image-guided therapy (IGRT) based on this can elevate radiotherapy accuracy to a new historical level. Image guidance ensures that patients receive the most accurate radiotherapy while greatly improving treatment efficiency. Patients can be positioned with just one click before treatment, and treatment can begin within 15-20 seconds after image guidance is completed.
