Wepresent analytical models of the dose-mean lineal energy (yD) and the saturation-corrected dosemean lineal energy (y∗) for fast and accurate radiobiological calculations in proton therapy. These models are based on the modelling of microdosimetri

Reference dosimetry in a scanned pulsed proton beam using ionisation chambers and a Faraday cup

Publikováno v: Physics in Medicine and Biology. 53:3519-3529

In order to give the correct dose to a patient, the monitor chamber for a proton scanning system has to be calibrated. As recombination of ion pairs occurs in the monitor chamber, the relation between the number of particles traversing it per time un

In this paper we present the recent developments made for the scanning system for proton beams at TSL in Uppsala, showing that this system is now fully functional being able to produce conformal intensity modulated scan patterns with sufficient accur

Parametrization and application of scatter kernels for modelling scanned proton beam collimator scatter dose

Autor: Peter Kimstrand, Nina Tilly, Erik Traneus, Anders Ahnesjö

Publikováno v: Physics in medicine and biology. 53(13)

Collimators are routinely used in proton radiotherapy to laterally confine the field and improve the penumbra. Collimator scatter contributes up to 15% of the local dose and is therefore important to include in treatment planning dose calculation. We

A beam source model for scanned proton beams

Autor: Bengt Glimelius, Anders Ahnesjö, Erik Traneus, Peter Kimstrand, Nina Tilly, Erik Grusell

Publikováno v: Physics in medicine and biology. 52(11)

A beam source model, i.e. a model for the initial phase space of the beam, for scanned proton beams has been developed. The beam source model is based on parameterized particle sources with characteristics found by fitting towards measured data per i
