Upright and supine particle therapy of lung cancer: A 4D dosimetric comparison. [PDF]

Med Phys
Abstract Background A renewed interest in upright particle therapy is currently driven by the availability of upright positioning and imaging systems. The upright positioning system could enhance fixed beamlines for effective carbon ion treatments in central body regions, with a substantial cost and space advantage.
