放射治疗成像与图像融合应用研究

Application of Image Guided Radiation Therapy

为了实现图像引导放射治疗(Image Guded Radation Therapy,IGRT)的临床应用,本文对医学图像融合技术在放射治疗中的应用进行了初步探讨。阐述了采用模拟定位机成像和医用直线加速器接口成像的图像融合用于患者治疗过程中摆位的验证。图像融合采用了基于Canny算子进行边缘特证提取的预处理方法,实现了特征级的图像融合。实验结果表明,本文所述算法是可行的,具有临床实用性。

For get image guided radiation therapy, research application of imaging amalgamation in radiation therapy. Expatiate the put in therapy with simulate orientation and beeline accelerator. For edge distilled character based Canny , achieved character image amalgamation.
