Due to the number of breathtaking developments in the field of medical imaging in recent years, the AAPM devoted the 1984 summer school to this topic. The papers from this sumer school fall into three categories-basic imaging theory, digital fluorographic systems, and digital radiographic systems. Papers are further divided into subcategories of physics and theory of operation, functional description and performance specifications, and acceptance and quality assurance testing. Digital subtraction angiography (DSA) is covered extensively in this book.
