For brain tumor treatment, head gamma knife is the best non-surgical treatment method. Head Gamma Knife is the “gold standard” of stereotactic radiosurgery for brain tumors, which is not only superior to other devices including X-knife, radio-wave knife, Tom Knife and linear gas pedal, but also the best means of simultaneous radiotherapy and chemotherapy. This is because the head gamma knife has three absolute advantages: (1) accurate three-dimensional positioning; (2) unparalleled three-dimensional spatial focus of radiation; (3) highly consistent three-dimensional conformal tumor. Head Gamma Knife dose splitting treatment, while having these three major advantages, also changed the head Gamma Knife’s one-time high dose irradiation to multiple repetitions of medium dose irradiation. This improvement makes head gamma knife treatment not only suitable for smaller tumors, but also for larger tumors will have satisfactory results. This includes large volume gliomas, large volume brain metastases, meningiomas, lymphomas, skull base tumors, etc.
