Measurement of gold nanofilm dose enhancement using unlaminated radiochromic film.
PURPOSE Bombarding high-Z material with x-ray radiation releases Auger electrons and Coster-Kronig electrons, along with deeper penetrating fluorescent x-rays and photoelectrons. The Auger and Coster-Kronig electron penetration distance is on the order of nanometers to micrometers in water or tissue, creating a large dose enhancement accompanied by a RBE greater than 1 at the cellular level. Th...
متن کاملEnhancement of MD-55-2 radiochromic film sensitivity using a multilayer film technique for applications in the low dose range
ABSTRACTBackgrounds: MD-55-2 is one of the Radiochromic film models with the sensitivity suitable for dose measurements ranging from 5 to 100 Gy. However, this lower limit makes the film impractical for its applications in many areas such as brachytherapy source dosimetry.Materials and methods: In this project, the useful range of the film has been extended by using a multilayer film techniqu...
متن کاملDose Distribution Evaluation and Independent Quality Check of Spherical INTRABEAM™ Applicators via Radiochromic EBT2 Film Measurement
Introduction: The present study was conducted to implement a simple practical independent quality check of depth dose and isotropy of the Intrabeam™ therapeutic X-ray machine using radiochromic EBT2 film. Material and Methods: Theindependent quality check of 1.5, 3.5, and 5-cm spherical Intrabeam™ applicators was accomplished using particular EBT2 film cutting pieces with internal rounded edge...

متن کاملIntraoperative radiation therapy in the treatment of early-stage breast cancer utilizing xoft axxent electronic brachytherapy
BACKGROUND In an effort to overcome the barriers to BCT, alternative methods of delivering radiation therapy have been explored. APBI allows the radiation treatment to be accomplished in one week or less. XB is a form of balloon-based APBI that uses an electronic source generated by a mobile controller unit. Investigators have also explored IORT treatment that delivers a single fraction of radi...
