A non-invasive relocatable stereotactic frame has been developed for fractionated stereotactic external beam radiotherapy (SRT) by linear accelerator. Fixation is via the upper dentition and tests of repositioning have shown mean antero-posterior and lateral displacements of 1.0 mm. The relocatable frame allows accurate 3-dimensional target localisation by CT, MRI, PET and cerebral angiography and precise isocentric positioning for radiotherapy. This method of immobilisation is ideal for fractionated SRT as well as for other techniques requiring high precision localisation and treatment delivery.
已开发出一种用于直线加速器分次立体定向体外照射放疗（SRT）的无创可重新定位立体定向框架。通过上牙列进行固定，重新定位测试显示前后和侧向平均位移为1.0毫米。这种可重新定位框架允许通过CT、MRI、PET和脑血管造影进行精确的三维靶区定位，并为放疗进行精确的等中心定位。这种固定方法对于分次SRT以及其他需要高精度定位和治疗投送的技术来说是理想的。
