Effect of dose rate on antitumor activity in hypoxic cells by using flattening filter free beams
Background: Recently, the Flattening Filter Free (FFF) beams, which allow a dose rate increase of up to four times compared to the normal dose rate, have been incorporated into radiation therapy machines. The aim of this study is to evaluate antitumor activity in hypoxic cells irradiated with different dose rates using FFF beams and to identify the casual mechanism for cellular damage during ir...
متن کاملInvestigation of Neutron Contamination of Flattening Filter and Flattening Filter-Free 10-MV Photon Beams in Elekta InfinityTM Accelerator
Introduction: This study aimed to measure the neutron contamination of flattening filter (FF) and flattening filter-free (FFF) 10-MV photon beams delivered by the Elekta InfinityTM accelerator. Material and Methods: The photoneutron spectrum produced by the Linac head was evaluated using a Monte Carlo (MC) simulation. The geometry ...

متن کاملClinically relevant investigation of flattening filter‐free skin dose
As flattening filter-free (FFF) photon beams become readily available for treat-ment delivery in techniques such as SBRT, thorough investigation of skin dose from FFF photon beams is necessary under clinically relevant conditions. Using a parallel-plate PTW Markus chamber placed in a custom water-equivalent phantom, surface-dose measurements were taken at 2 × 2, 3 × 3, 4 × 4, 6 × 6, 8 × 8, 10 ×...
متن کاملFPGA Can be Implemented Using Advanced Encryption Standard Algorithm
This paper mainly focused on implementation of AES encryption and decryption standard AES-128. All the transformations of both Encryption and Decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. This method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theAES InverseSub Bytes module and...
