Monte Carlo dosimetry for forthcoming clinical trials in x-ray microbeam radiation therapy.
The purpose of this work is to define safe irradiation protocols in microbeam radiation therapy. The intense synchrotron-generated x-ray beam used for the treatment is collimated and delivered in an array of 50 microm-sized rectangular fields with a centre-to-centre distance between microplanes of 400 microm. The absorbed doses received by the tumour and the healthy tissues in a human head phan...
متن کاملMOSFET dosimetry for microbeam radiation therapy at the European Synchrotron Radiation Facility.
Preclinical experiments are carried out with approximately 20-30 microm wide, approximately 10 mm high parallel microbeams of hard, broad-"white"-spectrum x rays (approximately 50-600 keV) to investigate microbeam radiation therapy (MRT) of brain tumors in infants for whom other kinds of radiotherapy are inadequate and/or unsafe. Novel physical microdosimetry (implemented with MOSFET chips in t...
متن کاملMicrobeam radiation therapy.
It is proposed to carry out radiotherapy and radiosurgery for brain lesions by crossfiring an array of parallel, closely spaced microbeams of synchrotron-generated x rays several times through an isocentric target, each microbeam in the array having an approximately 25-microns-wide adjustable-height rectangular cross section. The following inferences from the known tissue sparing of 22-MeV deut...
متن کاملCharacteristics, Dosimetry & Measurement of Emf
This paper describes characteristics of electromagnetic fields and their interaction with body as a fundamentals of electromagnetic field (EMF) safety issue. It also presents how engineering and physics contribute to this. EMF should be appropriately and precisely characterized when we consider its interaction with body. Dosimetry, which is the quantification of substance interacting with the e...
