调强适形放射治疗 (IMRT)是近几年随着计算机技术的应用而发展起来的一种放射治疗方法。同常规放射治疗技术相比 ,调强适形放射治疗技术的剂量分布可在三维方向上与靶区适形 ,并可使靶区内剂量分布更均匀 ,从而使靶区周边组织免受或不受照射。但由于治疗机的精度及逆向放射治疗
Intensity modulated radiation therapy (IMRT) is a radiotherapy method developed in recent years with the application of computer technology. Compared with conventional radiotherapy techniques, the dose distribution of intensity-modulated conformal radiotherapy can be conformally aligned with the target in three dimensions and the dose distribution in the target can be more uniform, so that the tissues around the target can be protected from or not Irradiated. However, due to the accuracy of the treatment machine and reverse radiotherapy
