Information obtained by different methods of image-guided radiotherapy now allows us to reposition the target volume. This evolution causes a change in practice and positioning control. In order to control positioning errors, a systematic control during the first three to five sessions is required. Random repositioning errors and clinical target volume motions can be mastered only by performing a daily imaging. Finally, image-guided radiotherapy allows assessing anatomical changes occurring during treatment, and opens the field of adaptive radiotherapy.
通过不同的图像引导放射治疗方法获得的信息现在使我们能够重新定位靶区体积。这种发展导致了实践和定位控制的变化。为了控制定位误差，在前三到五次治疗过程中需要进行系统的控制。只有通过每日成像才能掌握随机重新定位误差和临床靶区体积运动。最后，图像引导放射治疗能够评估治疗期间发生的解剖学变化，并开启了自适应放射治疗领域。
