| 摘要 |
The present invention relates to a reference means (1) comprising at least one reference marker (4) which is applicable temporarily or permanently in a patient's body at a specified location relative to a tumor in the body in order thereafter, by means of the reference marker (4), to enable precision aiming of a treatment beam at the tumor. For universal use and easy application of the reference marker, the reference marker (4) is so configured that it is displayable by both magnetic resonance tomography (MRT) and X-raying, preferably CT, in order to determine by MRT and/or X-raying, preferably CT, the location of the reference marker (4) relative to the tumor for subsequent precision aiming of the treatment beam, and the reference marker (4) is applicable, as desired, either temporarily in the body via a catheter (2) which forms part of the reference means (1) or permanently in the body via an insertion means (11) in the form of a catheter. |
