GKNS for uveal melanoma has become a recognized valued treatment which avoids enucleation of the eye. In the early days, the eccentric location of these tumors made treatment difficult, but Gamma Knife Perfexion has solved that problem. It is known that larger tumors and tumors with an anterior location have a worse prognosis.

Detection of the Indicated Area with an Indication Stick
2000This paper describes a detection method of indication action and the corresponding indicated area with a stick. In human communication, there exists ambiguity of indication action, so we need some useful knowledge about indication action. We propose a detection method of the indicated area based on the knowledge which we clarify by means of observation
