Radiation target points position detection appts. esp. for medical radiation therapy

摘要

The appts. has an anchoring device (10) for fastening to a patient reference system, esp. to a stereotactical immobilising system eg. a head brace. A marking device is attached to the anchoring device to mark at least one coordinate point in different spatial projections. The marking device is made of several computer printed flat materials spatially setting the coordinate points. The anchoring device is a rectangular, cubic or square housing, open on one side (E). The side surfaces (A,B,C,D) have recesses (11, 12, 13) for the computer printed flat material. The material is preferably a film with computer printed coordinate markings on the surface. The outline of the body to be irradiated is printed on the film.
