  • Radiotherapy system based on multi-isocenter
    Patent number: 12350520
    Abstract: A radiotherapy system based on multi-isocenter includes an accelerator and a three-sequence image-guided positioning system. The three-sequence image-guided positioning system includes multiple low-level image-guided positioning systems corresponding to a low-level treatment center and a high-level image-guided positioning system corresponding to a high-level treatment center. The high-level image-guided positioning system is arranged among the multiple low-level image-guided positioning systems. The intersection of two beams generated by any two image-guided positioning systems among the low-level image-guided positioning systems and the high-level image-guided positioning system is the low-level treatment center. A beam generated by the high-level image-guided positioning system passes through the high-level treatment center.
