1. Gamma Knife

Gamma Knife is a state-of-the-art instrument that integrates the sophisticated techniques of medical imaging, stereotactic location, computerized calculation and customized contouring of focused high-dose radiation. The invention of Gamma Knife allows the surgeon to operate on intracranial problems without opening the skull, which ushered in a brand-new branch of medical science-radiosurgery, as well as promoted the development of neurosurgery.

Indications:
A. Vascular diseases: arteriovenous malformations (AVM)
B. Brain tumors: including acoustic neuroma, meningioma, metastases, hypophysoma, pituitary ameloblastoma, pinealoma, angioblastoma, trigeminal tumor, chordocarcinoma, glioma, melanoma, etc (preferably tumors no larger than 3cm in diameter).

2. Peacock System for Intensity Modulated Radiation Therapy (IMRT)

Based on the sophisticated technique of 3-D stereotactic location, by varying the intensity of the beams across the radiation field according to user specifications, doses can be precisely tailored to the 3-D contour of the target. This means a higher and uniform dose to target and a minimum dose to surrounding normal tissues. Referred to as "guidance radiotherapy", Intensity Modulated Radiation Therapy brings about a revolution to the conventional radiotherapy, taking it to a higher level.

Indications:
At present, the technique is used to treat tumors in various locations of the human body, such as brain tumors, brain and neck tumors, lung cancer, esophagus cancer, breast cancer, hepatic cancer, pancreatic cancer, kidney cancer, prostate cancer and gynecological tumors, etc.
