Case-based CAD systems in breast imaging

Knowledge-based systems (KBS) is a general term used to describe artificial intelligence techniques that rely on domain-specific knowledge to solve a new problem within that domain. The ultimate role of knowledge-based systems is to support human decision-making, learning, and action [1]. In that respect, all breast imaging CAD systems developed for detection, diagnosis, risk assessment, prognosis and other applications are essentially different examples of KBS technology. What differentiate these CAD systems are mainly the application domain (determined by the imaging modality and the clinical task of interest) and the methodologies used to represent the domain-specific knowledge and make inferences.
