Influence of respiratory motion management technique on radiation pneumonitis risk with robotic stereotactic body radiation therapy. [PDF]

open access: yes, 2018
Purpose/objectivesFor lung stereotactic body radiation therapy (SBRT), real-time tumor tracking (RTT) allows for less radiation to normal lung compared to the internal target volume (ITV) method of respiratory motion management. To quantify the advantage

Effect of variations in atelectasis on tumor displacement during radiation therapy for locally advanced lung cancer [PDF]

open access: yes, 2017
Purpose Atelectasis (AT), or collapsed lung, is frequently associated with central lung tumors. We investigated the variation of atelectasis volumes during radiation therapy and analyzed the effect of AT volume changes on the reproducibility of the ...
