A real time imaging device for extended radioactive sources based on monolithic and hybrid position sensitive silicon sensors has been developed by the SUCIMA (silicon ultra fast cameras for electron and γ sources in medical applications) collaboration. In the following, results obtained imaging 90Sr and 144Ce brachytherapy sources are presented. Large area silicon strip detectors, read out by low noise charge integrating chips, have been used to measure the dose depth curves and the sources profiles in tissue equivalent material (according to the prescription of the American Association of Physicist in Medicine Task Group No. 60). All the performed measurements are validated by qualified GafChromic films comparison.
