Investigation of single-shot beam quality measurements using state of the art solid-state dosimeters for routine quality assurance applications in mammography

Purpose To assess if single shot acquisitions with solid-state dosimeters as well as Robson’s method could replace ionization chambers for tube output and HVL measurements, saving medical physicists time. Material and methods The energy responses of 4 solid-state dosimeters with automatic calculation of HVL were compared to ionization chamber measurements. Five anode/filter combinations were tested: Mo/Mo, Mo/Rh, Rh/Rh, W/Rh and W/Ag, from 24kVp...
