Medical radiography programs will appreciate having an economical textbook that focuses on the practical aspects of digital radiography. Nearly all textbooks to date claiming the title digital radiography have dealt primarily with the managerial aspects of the topic at the expense of any practical information on how digital imaging works and its clinical implications for the daily practice of radiography. The goal of this book is to provide an accurate and adequate description of all the aspects of digital images and digital equipment, and their implications for radiographic technique and clinical application in a student-friendly way by providing crisp, clear illustrations along with readable text. Many of the lucid illustrations in this textbook are from the author's comprehensive textbook, Radiography in the Digital Age (Charles C Thomas, 2018), to make digital radiography comprehensible to the student, but in this book the focus is only on digital topics and the facts are stated with such brief explanatory material as each topic will allow. Many digital topics are intimidating, and every attempt is made to reduce these topics to a descriptive, non-mathematical level that can be intuitively understood by the average student. A helpful glossary is included whenever a concise definition is needed for a particular term.
This is a textbook concentrating on digital imaging in a radiography department. As a radiographer I have used and reported both CR and DR images, and have been involved in departments transitioning between the two. The chapters are laid out in a good order, leading from the very basics of understanding the digital machine and how the images are produced, through to post-processing of images, and how they are best displayed, finishing with information about reporting screen quality, quality control for the machines and a final chapter introducing digital fluoroscopy. The information is worth the retail price. The content of each chapter is laid out well, with a good mix of pictures and diagrams breaking up the text. The use of radiography language helps to make it understandable, and walks you through the somes complex physics of image acquisition. There is good information on the capabilities and also the limitations of the equipment, and the quizzes at the end of each chapter help to cement the learning from the readings. There is an emphasis on image quality and an understanding that all radiographers should work to the ALARP principle, and how digital equipment can help this. It explains the issues with both under exposure and over exposure on image manipulation and reporting. As an American book it only mentions radiologists, but it is equally important for reporting radiographers to understand image manipulation. The information in the book would be beneficial to student radiographers and also has a place in the modern radiography department switching from CR to DR, or looking to understand the capabilities of their machinery and to get the best out of it. It will help with technical questions that may need to be asked of each manufacturer if new equipment is being sourced. I now understand more about the machinery and the imaging, and the relationship between the exposure index and the deviation index, and the limitation of manipulating the image at source for the reporter. The glossary at the end is a comprehensive list with explanation of all the teology we should all be aware of and often use, and is a good reference point to help the all-round knowledge needed to understand DR imaging. -Hilary Rose, reporting radiographer, Weston Area Health NHS Trust / RAD Magazine / February 2020
