Dual-source dual-energy CT with additional tin filtration: Dose and image quality evaluation in phantoms and in-vivo

PURPOSE: To investigate the effect on radiation dose and image quality of the use of additional spectral filtration for dual-energy CT (DECT) imaging using dual-source CT (DSCT). MATERIALS AND METHODS: A commercial DSCT scanner was modified by adding tin filtration to the high-kV tube, and radiation...
