Abstract:
Objective To assess the feasibility of ESD measurements in the mammography by the comparative study of energy dependence of the three passive solid detectors on low energy X-ray.Methods Two thermoluminescent TL) detectors ( LiF(Mg,Ti) and LiF( Mg,Cu, P) and one optically stimulated luminescence (OSL) detector( Al2O3: C ) were irradiated for the same air kerma by ten kinds of beam quality between 25-40 kV in a Mo/Mo low energy X-ray generator,respectively. Results The energy dependences of TL and OSL were 25% and 11% between 25-40 kV, respectively. Conclusions considerable potential for OSL detector can be used in routine quality control and ESD measurements in the mammography.
