| Abstract: | A non-invasive head fixation system is described which is accurately relocatable and enables the transfer of stereotactic positions between a variety of radiodiagnostic images and therapeutic procedures. The system can be simply and repeatedly applied for planning stereotactic radiation therapy from one or more diagnostic images and for repeated treatment with a conventional linear accelerator. In addition, the long-term effects of therapy can be objectively monitored by relocating the frame and repeating images in an identical way, months or years later. |
