Abstract For 3D optically stimulated luminescence (OSL) based dosimeters to be clinically applicable, certain standards must met. Among these are low detectable doses with high accuracy and precision, ideally comparable those of point-like detectors. By investigating a model the central part an OSL readout-system, we present estimate <?CDATA $\sim 4\cdot {10}^{7}\frac{{\rm{photons}}}{{\rm{Gy}}\...

introduction: the complex geometry of breast and also lung and heart inhomogeneities near the planning target volume (ptv) result in perturbations in dose distribution. this problem can result in overdosage or underdosage in the match region of the three treatment fields. the purpose of this study is to create a homogeneous dose distribution in the match region between the supraclavicular and t...

A new three-dimensional dosimetry technique using x-ray computed tomography (CT) to analyse polymer gels is proposed. The CT imaging is sensitive to radiation-induced density changes that occur within irradiated polyacrylamide gel (PAG). In this preliminary study, a CT imaging protocol is developed to optimize CT images of PAG; the response of PAG CT number to dose (N(CT)-dose response) and the...
