Whole Body Gamma Knife is a kind of stereotactic radiosurgery treatment equipment that integrates modern computer technology, stereotactic technology and radiosurgery technology to treat body diseases. After receiving signals from CT or MRI, the gamma rays are geometrically focused, and through precise stereotactic orientation, a certain dosage of gamma rays is planned to be focused on the pre-illuminated target point, which lethally destroys the tissues within the target point, so as to achieve the effect of surgical resection or destruction. Due to the method of rotational focusing of the ray, so that the ray through the normal tissues of the human body only by the instantaneous, almost harmless irradiation, and the dose is sharply reduced, so its therapeutic irradiation range and the normal tissue boundaries are very obvious, the edge of the knife like cut, people image called “Gamma Knife”. Indications: 1. Chest: esophageal cancer, primary lung cancer, lung metastatic cancer, cardiac malignant tumor, thymic carcinoma, primary and metastatic mediastinal tumors, etc. 2. Abdomen: primary liver cancer, metastatic liver cancer, metastatic intrahepatic carcinoma after liver transplantation, pancreatic cancer, gallbladder cancer, cholangiocarcinoma, pancreatic carcinoma, sigmoid colon carcinoma, gastric carcinoma, colon carcinoma, rectal carcinoma, and retroperitoneal cancer, primary or metastatic cancer. Urological and genitourinary tumors: kidney cancer, adrenal tumor, prostate hyperplasia, prostate cancer, bladder cancer, testicular tumor and metastasis, etc.; gynecological tumors: cervical cancer, uterine cancer, fallopian tube cancer, ovarian cancer, pelvic primary and metastatic cancers, etc. Bone tumors: osteosarcoma, osteoblastoma, cervical, thoracic, lumbar spine, pelvic bone metastatic tumor, spinal cord tumor, metastatic tumor in spinal cord; 4. Lymph node metastatic cancer: neck, supraclavicular, axillary and inguinal.
