The imaging aspects of radiography have undergone con many sources and was in general freely given when requested siderable change in the last few years and as a teacher of and this is gratefully acknowledged. In particular I would radiography for many years I have often noticed the lack of a like to express my sincere thanks for help and information to comprehensive reference book for students. This book is an Mr J. Day of DuPont (UK) Ltd. particularly for the infor attempt to correct that situation and I hope this text will be mation and illustrations in the chapter on automated film of value not only to student radiographers but also prac handling; Mr D. Harper and Mr R. Black of Kodak Ltd. ; tising radiographers as well. Fujimex Ltd. ; CEA of Sweden; 3M (UK) Ltd. ; Wardray Much of the information is based on personal experiment Products Ltd. ; D. A. Pitman Ltd. ; Agfa-Gevaert; PSR Ltd. and the knowledge gained of students' difficulties in studying for their help with information on silver recovery, and this subject. I have attempted to gather together in one book Radiatron Ltd. for their help with safelighting. All were most all the information required to understand the fundamentals helpful in my many requests for information. of the subject both for examination and for practice. Some To Mrs A.

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.

Advances in digital technology led to the development of digital x-ray detectors that are currently in wide use for projection radiography, including Computed Radiography (CR) and Digital Radiography (DR). Digital Imaging Systems for Plain Radiography addresses the current technological methods available to medical imaging professionals to ensure the optimization of the radiological process concerning image quality and reduction of patient exposure. Based on extensive research by the authors and reference to the current literature, the book addresses how exposure parameters influence the diagnostic quality in digital systems, what the current acceptable radiation doses are for useful diagnostic images, and at what level the dose could be reduced to maintain an accurate diagnosis. The book is a valuable resource for both students learning the field and for imaging professionals to apply to their own practice while performing radiological examinations with digital systems.
