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 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 کاملCharacterization and quantification of cerebral edema induced by synchrotron x-ray microbeam radiation therapy.
Cerebral edema is one of the main acute complications arising after irradiation of brain tumors. Microbeam radiation therapy (MRT), an innovative experimental radiotherapy technique using spatially fractionated synchrotron x-rays, has been shown to spare radiosensitive tissues such as mammal brains. The aim of this study was to determine if cerebral edema occurs after MRT using diffusion-weight...
متن کاملA first generation compact microbeam radiation therapy system based on carbon nanotube X-ray technology.
We have developed a compact microbeam radiation therapy device using carbon nanotube cathodes to create a linear array of narrow focal line segments on a tungsten anode and a custom collimator assembly to select a slice of the resulting wedge-shaped radiation pattern. Effective focal line width was measured to be 131 μm, resulting in a microbeam width of ∼300 μm. The instantaneous dose rate was...
متن کاملMagnetometer and X-ray Microbeam Comparison
This article concerns replicability of past results and consistency in data collection using X-ray microbeam and magnetometry, two prominent instruments for speech movement tracking. The same speaker was recorded on both instruments reading identical stimuli and using parallel experimental procedures and the same physician for transducer placement. Data from two X-ray microbeam (XRMB) runs were...
