Microdosimeters For Therapy

Tour Leader: Indra Das, NYU Langone Medical Center, New York, NYTour Guides:Hsui Ai, Indiana University School of Medicine, Indianapolis, INAaron Andersen, Indiana University School of Medicine, Indianapolis, INOlga Volotoskova, NYU Langone Medical Center, New York, NYParticipating Vendors:IBAPTW – New YorkRTI Electronics, Inc.Standard Imaging, Inc.Sun Nuclear CorporationSmall fields are increasing used in specialized radiation treatments such as Gammaknife, Cyberknife, Tomotherapy, IMRT, VMAT, SRS and SBRT. Due to small field size electron transport creates lateral electronic disequilibrium and thus dosimetry could be very difficult. Microdetectors are used for small field dosimetry which will be discussed in preface of this tour as below: •Understanding small field e.g. meaning and definition of small field•IAEA definition and approach•Characteristics of microdetectors in terms of perturbation, recombination, correction•Suitability of microdetectors in small field dosimetry
