Because lung cancer is a common and deadly cancer, several studies are underway to develop new lung cancer therapies. Currently, the treatment of choice for patients with early-stage non-small cell lung cancer who can tolerate surgery is direct surgical removal of the lung tumor (lung cancer surgery). Treatment options for patients who cannot tolerate lung cancer surgery (i.e., cannot undergo surgery due to medical factors) are external radiation therapy, stereotactic radiation therapy, and stereotactic radiosurgery. Advanced non-small cell lung cancer will be treated with surgery, stereotactic radiosurgery, stereotactic radiotherapy, chemotherapy, or a combination of these therapies depending on the severity of the disease, the size of the lung tumor, and the presence of metastases. The radio wave knife is the only device that uses real-time image guidance technology, which includes two sets of diagonal (90 degree crossed X-ray) X-ray image developers to detect the displacement of the tumor target area on the X-ray image in real time during the “surgery” process, and to dynamically irradiate the lung cancer lesions that move with breathing and make real-time compensation correction to ensure This ensures the accuracy of “surgery”, so that the radiation is completely irradiated on the lung cancer lesion without harming other surrounding tissues, and plays the role of protecting normal tissues, so that patients have no abnormal reaction after treatment and have fewer side effects.
