SU-E-T-01: Applications of 6MV FFF Photon Beams in Optimizing Radiobiological Response for Respiratory-Gated Liver SBRT.
PURPOSE To establish a radiobiological basis for gated stereotactic body radiotherapy of primary and metastatic liver cancers using volumetric arc radiotherapy in a flattening filter free (FFF) mode. METHODS Human cervical carcinoma, SiHa, non-small cell lung carcinoma, H460, and Chinese hamster V79 cells were irradiated in a water bath with 6MV photons from a Varian TrueBeam linear accelerat...
متن کاملCalculation of Correction Factors for Dosimeters Thermoluminescent of Lithium Fluoride (LiF-100) for Use in 6MV Photon Beams
Since the beginning of its use, radiation has already presented harm, justifying the necessity of controlled use. In order to monitor its effects and even avoid them, dosimetry has arisen. For the purpose of ensured all the necessary safety and monitor areas where there is radiation use, a lot of devices able to identify and quantify many types of radiation were developed. However, some these d...
متن کاملDosimetric Comparison between 6MV Flattened Filter and Flattening Filter Free Photon Beams in the Treatment of Glioblastoma with IMRT Technique: A Treatment Planning Study
Introduction: The present study evaluated the dosimetric comparison between 6MV flattened filter (FF) and flattening filter-free (FFF) photon beams in intensity-modulated radiation therapy (IMRT) technique for the treatment of glioblastoma (GBM) patients. Material and Methods: The present study was conducted on 10 patients with GBM previously...
متن کاملChoice of a Suitable Dosimeter for Photon Percentage Depth Dose Measurements in Flattening Filter-Free Beams
The International Atomic Energy Agency Technical Reports Series-398 code of practice for dosimetry recommends measuring photon percentage depth dose (PDD) curves with parallel-plate chambers. This code of practice was published before flattening filter-free (FFF) beams were widely used in clinical linear accelerators. The choice of detector for PDD measurements needs to be reassessed for FFF be...
متن کاملIn-vitro study of Radioprotection Effects of Cerium Oxide Nanoparticles in Exposure to MRC-5 Fibroblastic Cell lines with 6MV Photon Beams Using MTT Assay
Introduction: Recently Cerium oxide nanoparticles (CONPs) are being checked as interventional treatments in biological systems. The scavenging of free radicals by nanoparticles performance is the inhibition of Reactive Oxygen Species (ROS). Ionizing radiations can prevent the proliferation and differentiation of cells and even cause apoptosis. CONPs, as radioprotection, can pro...
