摘要：

Real-time dosimetry is a critical issue in most radiotherapy applications. Silicon Ultra fast Cameras for electron and gamma sources In Medical Applications (Nucl. Phys. B 125 (2003) 133) is an EC project addressing the development of an imaging device for extended radioactive sources based on monolithic and hybrid-position-sensitive silicon sensors. Large-area Silicon strip detectors read out by low noise charge integrating chips were used to characterize a Sr-90 intravascular brachytherapy source in terms of dose-depth curves in a tissue equivalent material and homogeneity of the activity. The results obtained with the Silicon sensor were compared to measurements with standard certified systems and are reported in the paper. (C) 2004 Elsevier B.V. All rights reserved.
