According to a statement of Gordon Moore computer performance doubles every 18 months. So it is not surprising that the "half-time" of modern computers is rapidly decreasing. Increasing demands of public health for radiology together with a rapid development of information technology and innovations result in a digital environment, where thorough guidance is necessary. This book is such a solid guidance for radiologists and other medical staff working in this field. The second edition has been brought up-to-date, revised and new aspects have been incorporated that focus on the synergy that results from the integration of digital systems used in radiology such as image fusion, "functional" imaging, electronic patient records and health networks, etc. It is intended for radiologists and all other physicians, as well as technicians, scientists, IT-experts, health care providers and health maintenance organisations. The IT-market now has changed so much that Integrated Health Care Enterprise becomes reality.
