  The Treatment Planning System (TPS) in radiotherapy often faces challenges in optimizing techniques for large tumor volumes due to mechanical limitations, such as the over-travel distance of the Multileaf Collimator (MLC). This study compares the dosimetric outcomes of split field and open field techniques in Volumetric Modulated Arc Therapy (VMAT) for carcinoma tongue patients with large target volumes. Twenty-one patients treated with VMAT were evaluated using Eclipse™ TPS. The dosimetric parameters including conformity index, homogeneity index, and dose to Organs at Risk (OAR) were compared between split and open field techniques. Methods: VMAT plans utilizing two arcs were generated in Eclipse™ TPS with 6MV photon beams on a Truebeam STx Linear accelerator for all patients using both split and open field techniques. In the split field technique, fields were s.. Read More»
