Abstract :
In order to accurately visualize and delineate certain liver tumors on four-dimensional or breath-hold computed tomography images, synchronized intravenous contrast injection is used during simulation at our institution. The purpose of this study is to present these two tumor motion management techniques used for tumor delineation and treatment delivery.
