臨床醫生使用一種更加精確的技術成功地治療了一例肺癌患者，該技術使用影像引導放射治療(IGRT)與呼吸調控系統，在適應呼吸運動的同時進入腫瘤。

這種保留組織的手術是由Pittsburgh大學醫學中心(UPMC; Pittsburgh, USA)癌癥中心的臨床醫生進行的，使得利用Varian醫學系統公司(Palo Alto, CA, USA)的尖端成像和治療技術成為可能。UPMC醫療小組特別設計了患者治療方法，能夠保護心臟和食管，以及肺臟的健康部分。

Dynamic靶向IGRT治療方法使用Varian公司的Trilogy線性加速器配備了車載成像儀，用于監測腫瘤運動和RPM(實時位置控制)呼吸調控系統，與患者自然呼吸循環同步輸送光束。
 
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.
