Dosimetry

Breast cancer diagnose techniques, such as mammography and tomosynthesis, make use of x-ray beams with kilovoltage peaks ranging from 25 kV to 36 kV to obtain digital images of the organ. Dose monitoring is necessary to avoid patients' over exposure, due to patient repetitive examination or machine malfunction. In this study, we exploit the energy and temperature dependencies of a polyvinyltoluene plastic scintillator (BC-404 from Saint-Gobain) used as dosimeter. Measurement were performed with a Siemens Mammomat tomograph at Hospital da Luz, Lisbon and in the laboratory of the Faculty of Sciences of the University of Lisbon.
