Abstract

Use of an implant having magnetic properties for reproducible determination of the position of a patient in time in relation to external treatment equipment, and an apparatus for reproducibly determining the position of a patient in relation to external treatment equipment. The apparatus comprises at least one magnetic device (1) which is so designed that it can be attached to a body part, the position in relation to the intended treatment target is substantially constant, and at least one sensor means (4) which is capable of detecting magnetic fields and/or changes of magnetic fields for determining the position of the patient in the space based thereon.
