Purpose: To investigate the dosimetric accuracy of sliding window gated IMRT compared with static treatment, using varying dose rates.Materials and methods: This study measured changes in output diode array response changing rate, verified precision motion table, distribution film diodes at two depths rate.During 4DCT (4 Dimensional Computed Tomography), patient's respiratory signals target were recorded imported to XY4D simulation table SUN NUCLEAR Corporation simulate respiration tumour motion.A single field each plan 30º wedge one for lung cancer used this study.Three irradiating conditions, moving without gating, applied both plans.Results: The standard deviations output, rates from 300-600 MU/min, 0.065 cGy 0.169 ionisation chamber diode, respectively.The verification shows very good 9.98 ± 0.02 cm (true value = 10.0 cm).The measurements by MapCheck show gamma index planned absolute targets resulting more than 96% passing all rates.The was agreeable gating. Conclusion:The technique is able deliver an accurate a rate MU/min that suitable clinical treatment.
