On-line compensation of dose changes caused by intrafractional tumor motion

Background: Tumor therapy using scanned ion beams requires motion mitigation for treatment of intra-fractionally moving tumors. Our preferred motion mitigation technique is beam tracking because it potentially allows best dose conformity for moving tumors. Beam tracking compensates target motion [for full text, please go to the a.m. URL]
