Description
Summary: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 90Sr 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.
