Master's thesis of Applied Physics (Medical & Health Physics) : The reduction of dose to breast tissue during multi-slice CT examinations using bismuth breast shields and dose modulation technologies

The overall aim of this study is to determine the most effective way to reduce the radiation dose to the breast during non-breast related CT scans, whilst still maintaining a suitable image quality. This study will attempt to compare the doses and noise of various protocols that can be used for dose reduction, including tube current modulation, bismuth breast shields and manual reduction of tube current.
