title: Programmable segmented volumetric modulated arc therapy for respiratory coordination in pancreatic cancer.
abstract: We programmably divided long-arc volumetric modulated arc therapy (VMAT) into split short arcs, each taking less than 30s for respiratory coordination. The VMAT plans of five pancreatic cancer patients were modified; the short-arc plans had negligible dose differences and satisfied the 3%/3-mm gamma index on a MapCHECK-2 device.
