浅析数字化影像在放射治疗质量保证中的应用

Application of Digital Images in Quality Assurance of Radiotherapy

通过各种KV级、MV级实时数字化影像和三维重建影像在放疗质量保证中的应用,为放疗射野中心及治疗范围的验证、摆位精度校正和放疗设备和物理特性检查方面提供了有效的手段,使得放射治疗的质量和精度都得到很大提高。

The application of KV, MV real-time digital images and 3D reconstructed radiography in quality assurance of radiotherapy, provides effective means to verify the beam center and therapeutic range, calibrate the positioning accuracy and inspect the characteristics of radiotherapy equipment and radiation physics, greatly improves the quality and accuracy of radiotherapy.
