Principles of Fluoroscopic Image Intensification and Television Systems

". . . written primarily for students enrolled in radiography training programs. . . appealing because few radiographic textbooks provide a . . . discussion of the cameras and closed-circuit television systems used in fluoroscopic imaging."-RadiologyReview:"I highly recommend this book for use by any student or professional seeking to improve their understanding."Beth Graff, Imaging Specialist, Arnold Palmer Hospital for Women & Children, Orlando, Florida
