Treatment planning for the lung cancer

Abstract

Letter to editorVolumetric modulated arc therapy (VMAT) and intensity modulated radiation therapy (IMRT) are commonly used treatment techniques for cancer treatment, and both the VMAT and IMRT techniques use the photon beam (mega-voltage X-rays) to deliver radiation dose to the tumor. The capability of modulating radiation beam has increased the ability of delivering more conformal dose distributions to tumor volume while minimizing dose to the normal tissues. The VMAT planning generally involves one or multiple arcs with gantry rotating around the patient, whereas the IMRT planning involves multiple static beams.
