Description:
This fourth edition of Understanding Radiography not only contains
updated and refreshed material on familiar imaging technology, it also
provides thorough explanations with many original illustrations of high
speed CT imaging, PACS networks, computerized and direct digital
radiography. Further, it contains new insights that will help prepare
students for board exams. Experienced technologists will benefit
through a broader understanding of the associated terminology, and how
these technologies can be used to provide the highest level of imaging
services possible. Chapters have undergone revision and new knowledge
relating to equipment, methods, techniques and procedures have been
assembled. Two chapters on PACS Network Imaging are included that cover
the latest advanced technology for producing, storing and transmitting
images, which will eventually replace conventional film methods in most
facilities. Chapter objectives appear at the beginning of each chapter,
and a set of study questions appear at the closing of each chapter that
will help prepare students for registry exams. Experienced
technologists will also benefit by gaining a broader understanding of
how these advanced technologies can be used to provide the highest
level of imaging services. As always, great care has been taken to
provide a blend of the basic technical factors, their relationship to
physics, and their applicability to typical situations with which the
technologist will be confronted. Information on conventional imaging
has also been expanded regarding tabular grain film and high frequency
generators, radiation protection, x-ray tubes, and digital imaging. The
nature of the radiographic image, film and processing, intensifying
screens, focal distance, and the remnant beam are among the major
subjects that are updated. Hundreds of drawings and radiographic
reproductions are discussed throughout the book and many of these have
been revised.
