  Objective: This study aims to evaluate Intensity Modulated Radiotherapy (IMRT) and Rapid Arc based on Flattening Filter (FF) and Flattening Filter Free (FFF) beams. Materials and Methods: Twelve patients with single brain metastases and dose prescription 25Gy in 5 fractions are selected and for each patient, both IMRT and Rapid arc plans are created with and without FF. All plans are analysed and compared based on various dosimetric parameters for Planning Target Volume (PTV) and Organ at Risks (OARs) along with technical parameters. Results: The results among PTV dosimetric parameters improved with Rapid Arc plans from IMRT in both FF and FFF modes like the D98% bettered as (23.59 ± 0.85) and (23.65 ± 1.16) respectively with P values 0.011 and 0.025. The D80% of FFF arc plan has P value 0.030 with dose value (24.89 ± 0.59) and HI95% of both FF.. Read More»
