PURPOSE To assess the role of reoxygenation of hypoxic tumor cells in hypofractionated radiotherapy of prostate cancer. METHODS The considered radiobiological model is based on the assumption of two populations (compartments) of cells: oxygenated (ae

The purpose of this study is to describe four new delivery schemes for intensity-modulated radiation therapy(IMRT). In the first two schemes the order in which segments are delivered is varied from fraction to fraction. The last two delivery schemes

The aim of this study is to evaluate how simultaneously increasing fraction time and dose per fraction affect biologically effective dose for the target (BED(tar)) while biologically effective dose for the normal tissue (BED(nt)) is fixed.In this inv

The effect of radiation protraction in step-and-shoot IMRT is investigated for treatment plans created with the help of direct aperture optimization. The latter approach can be used during inverse planning for all clinical linear accelerators with co

With conventional Fourier transform (FT) magnetic resonance imaging (MRI), it is difficult to perform contrast-enhanced three-dimensional (3D) MR angiography (MRA) with the temporal and spatial resolution necessary to depict the carotid arteries. How
