新型放射治疗肺癌靶向移动肿瘤

 
临床医生使用一种更加精确的技术成功地治疗了一例肺癌患者，该技术使用影像引导放射治疗(IGRT)与呼吸调控系统，在适应呼吸运动的同时进入肿瘤。

这种保留组织的手术是由Pittsburgh大学医学中心(UPMC; Pittsburgh, USA)癌症中心的临床医生进行的，使得利用Varian医学系统公司(Palo Alto, CA, USA)的尖端成像和治疗技术成为可能。UPMC医疗小组特别设计了患者治疗方法，能够保护心脏和食管，以及肺脏的健康部分。

Dynamic靶向IGRT治疗方法使用Varian公司的Trilogy线性加速器配备了车载成像仪，用于监测肿瘤运动和RPM(实时位置控制)呼吸调控系统，与患者自然呼吸循环同步输送光束。
 
Novel Radiotherapy for Lung Cancer Targets Moving Tumors
 
Clinicians have successfully treated a lung cancer patient using a more precise technique that combines image-guided radiotherapy (IGRT) with respiratory gating to narrow in on the tumor while adapting for breathing motion.

The tissue-sparing procedure, performed by clinicians at the University of Pittsburgh Medical Center (UPMC; Pittsburgh, USA) Cancer Centers, was made possible using sophisticated imaging and treatment technology from Varian Medical Systems (Palo Alto, CA, USA). The UPMC medical team specially designed the patient’s treatment to protect the heart and esophagus as well as the healthy parts of the lung.

The Dynamic Targeting IGRT treatment was delivered using Varian’s Trilogy linear accelerator equipped with an On-Board Imager for monitoring tumor motion and the RPM (real-time position management) respiratory gating system for synchronizing beam delivery with the patient’s natural breathing cycle.
