All medical imaging modalities require an explicit selection of techniques (such as kV and mA/s) and other parameters (geometry, grids, etc) to enable any image to be generated. The choices available today are increasing, primarily because of the advent of digital imaging. Any choice will impact on both the radiation dose and the corresponding image quality, impacting on diagnostic information. Topics to be covered: • Medical image formation, and measures of image quality • Medical radiation dosimetry, and radiation risks/uncertainties • CR/DR (1.5 hours).Fluoroscopy • Angiography/DSA • CT • Mammography Participants will have an enhanced understanding as to how choices they make in developing imaging protocols will impact on the amount of radiation the patient will receive, and the corresponding image quality (diagnostic performance). Information presented in the course should help participants to use imaging equipment to minimize patient doses without sacrificing diagnostic performance, resulting in improved patient care.
