Bismuth-silicon and bismuth-polyurethane composite shields for breast protection in chest computed tomography examinations

The article aims at constructing protective composite shields for breasts in chest computed tomography and investigating the effects of applying these new bismuth composites on dose and image quality. Polyurethane and silicon with 5% of bismuth were fabricated as a protective shield. At first, their...
