Image-guidance plays a crucial role in positioning the target during stereotactic body radiotherapy (SBRT). Despite current limitations, on-line kilo-voltage cone-beam computed tomography (CBCT) also has the potential to identify changes in target volume geometry and the location of important organs at risk. These capabilities could be enhanced by further technical improvements in CBCT, including image quality.
图像引导在立体定向体部放射治疗（SBRT）中对靶区定位起着至关重要的作用。尽管目前存在局限性，但在线千伏级锥形束计算机断层扫描（CBCT）也有潜力识别靶区体积几何形状的变化以及重要危及器官的位置。CBCT在图像质量等方面的进一步技术改进可以增强这些功能。
