Gamma Knife Center

Stereotactic radoosurgery using Gamma Knife, which is called as "invisible blade" or "Surgery without Knife" is ready to operate on patients with various intracranial conditions, including brain neoplasms or vascular malformations, at Gamma Knife Center of Komaki City Hospital in Japan. Gamma Knife is believed to be the most precise device for radiosurgery. Recently, Gamma Knife treatment is reported to be useful for some functional disorders, such as trigeminal neuralgia. Gamma Knife is now working at about 195 sites in the world and at 42 in Japan. About 190.000 patients were treated all over the world. Among them 50,000 patients were treated in Japan. We installed a Gamma Knife in May, 1991 and have treated more than 5,000 patients. We have obtained excellent treatment results.

Introduction of Gamma Knife model C

The Gamma Knife model C was introduced in Octorber, 2004. This model has an excellent system called APS (Automatic Positioning System) which automatically moves the patient's head to a number of target coordinates defined in the treatment plan. Before the introduction of APS, the patients were set up manually. This new model achieved shorter treatment time, more accurate irradiation, and no manual mistake. In regard to dose planning, the coordinates can be set up with an accuracy of 0.1 mm rather than 0.5 mm which is the limit in the old model. By the Introduction of this new model, better tumor control and functional outcomes would be expected.
