Digital Radiography: An Introduction for Technologists, presents the physical principles and technical description of digital radiography imaging systems and associated technologies. This book functions as both a primary source for introductory digital imaging courses and as a reference for radiologic technologists and other imaging personnel. The book begins by exploring the many digital image acquisition imaging modalities such as computed radiography (CR), flat-panel digital radiography, digital fluoroscopy, and digital mammography systems in detail, followed by an outline of the essential elements of digital image processing. Associated technologies such as picture archiving and communication systems (PACS) and medical imaging informatics (MII) are also outlined. Finally, the book concludes with a description of quality control procedures for digital radiography.

Das Buch ist ein globales Phänomen. Es wurde 3,5 Millionen Mal verkauft, in rekordverdächtigen 43 Sprachen publiziert und ist auf 5 Kontinenten zum Bestseller geworden. Nun ist es in einer aktualisierten und erweiterten Auflage neu erschienen. - Der internationale Bestseller: Jetzt mit neuem Vorwort, neuen Kapiteln und aktualisierten Fallstudien - Ein Bestseller auf 5 Kontinenten - Weltweit mehr als 3,5 Millionen Bücher verkauft - In 43 Sprachen übersetzt - Ein Wall-Street-Journal-, Businessweek- und Fast-Company-Bestseller Der von Organisationen und Branchen auf der ganzen Welt hochgeschätzte Bestseller stellt alles in Frage, was wir bisher über die Voraussetzungen strategischen Erfolgs zu wissen glaubten. Der Blaue Ozean als Strategie, vertritt die Ansicht, dass ein brutaler Konkurrenzkampf nur dazu führt, dass sich die Konkurrenten in einem blutrot gefärbten Ozean um rapide schwindende Gewinnmöglichkeiten streiten. Basierend auf der Untersuchung von mehr als 150 strategischen Schachzügen (im Lauf von mehr als 100 Jahren und in mehr als 50 Branchen) vertreten die Autoren die Ansicht, dass nachhaltiger Erfolg nicht auf verschärftem Konkurrenzkampf, sondern auf der Eroberung »Blauer Ozeane« beruht: der Erschließung neuer Märkte mit großem Wachstumspotenzial. Der Blaue Ozean als Strategie präsentiert einen systematischen Ansatz, wie man Konkurrenz irrelevant macht, und legt Prinzipien und Methoden vor, mit der jede Organisation ihre eigenen Blauen Ozeane erobern kann. Diese erweiterte Auflage enthält: - Ein neues Vorwort der Autoren: Hilfe! Mein Ozean färbt sich rot. - Aktualisierungen der in dem Buch behandelten Fälle und Beispiele, indem ihre Geschichte bis in die Gegenwart weitervorfolgt wird. - Zwei neue Kapitel und ein erweitertes drittes Kapitel: Ausrichtung, Erneuerung und Red Ocean Traps. Sie behandeln die wichtigsten Fragen, die die Leser in den vergangenen zehn Jahren gestellt haben. Der bahnbrechende Bestseller stellt das bisherige strategische Denken auf den Kopf und entwirft einen kühnen neuen Weg in die Zukunft. Hier können Sie lernen, wie man neue Märkte erschließt, auf denen Konkurrenz noch keine Rolle spielt. "Das ist ein extrem wertvolles Buch." Nicolas G. Hayek, Verwaltungsratpräsident, Swatch Group "Ein Muss für Manager und Wirtschaftsstudenten." Carlos Ghosn, President und CEO, Nissan Motor Co., Ltd.
