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.According to a statement of Gordon Moore, the founder of Intel Corporation, computer performance doubles every 18 months. So it is not surprising that the half-time of modern computers is rapidly decreasing, meaning computer based radiology equipment ages very fast. Increasing demands of public health for radiology together with a never-ending rapid development of information technology and innovations result in a digital environment, where careful and thorough guidance is necessary.The book Digital (R)evolution in Radiology (2001), edited by Walter Hruby, MD, is such a solid guidance for radiologists and other medical staff working in this field. As Jack I. Eisenman, MD, puts it in his review of this book, The editor and the authors are authorities who have contributed to adapting, in a user-friendly manner, the digital (r)evolution to the needs of people who operate medical information systems (Radiology, April 2002).Almost three years after the first editionl3
