As the radiation Oncology community is faced with challenge to achieve very conformal dose distribution while trying to improve local control through dose escalation, the precise location of the target volume and clinical structures have never been more critical. Multi-modality imaging fusion provides us a better way to contour the tumor volume as well as normal tissue. PET-CT, MRI-CT and CT-CT image fusion have been performed on Philips/ADAC treatment planning prior to IMRT planning.

为了通过增加剂量的方式改善肿瘤的局部控制，放射肿瘤学界面临的挑战是实现适形的剂量分布，因此靶区和临床感兴趣结构的精确定位就变得至关重要。图像融合技术为勾画肿瘤区和正常组织提供了一种很好的方法。我们在实施调强放射治疗计划前在Philips/ADAC治疗计划系统上进行了PET-CT、MRI-CT 和CT-CT的图像融合。
