    The goal of the current study was to compare radiotherapy treatment plans for gastric cancer using double-arc volumetric (VMAT), Intensity-Modulated Radiotherapy (IMRT) versus 3DCRT delivery techniques. Materials and Methods: A total of 20 gastric cancer patients were involved in current study and each patient was scheduled IMRT VMAT and 3DCRT techniques. Dose-volume histogram statistics, Conformal Index (CI), hand Monitor Units (MUs) were analysed to compare treatment plans, treatment planning system eclipse Algorithm AAA with Energy true beam linear accelerator Varian model. Results and Discussion: The VMAT plans exceeded the other two techniques for coverage planning tumour volume dose and reduction dose for organs at risk in the kidneys, but not in the liver. VMAT exhibited a better mean CI (0.89±0.03), than the other techniques. In addition, for the kidneys the dose sparin.. Read More»
