Amazon.com description: Product Description: This new Seventh Edition is a most expansive and comprehensive text on radiographic exposure and imaging and encompasses the vast and intricate changes that have taken place in the field. As with previous editions, the book is intended to complement radiographic physics texts rather than duplicate them. It bridges the gap between theory and practice, and therefore assumes some basic knowledge of physical principles upon which the concepts of practical technique can be built. This volume also attempts to bridge the gap between quality control and technique. Part I, Producing the Radiographic Image, presents chapters on x-rays and radiographic variables, recording the permanent image, qualities of the image, and interactions of x-rays within the patient. Part II, Visibility Factors, includes chapters on milliampere-seconds, kilovoltage-peak, machine phase and rectification, beam filtration, field size limitation, patient status and contrast agents, pathology and casts, scattered radiation and image fog, grids, intensifying screens, and image receptor systems. Part III, Geometrical Factors, discusses focal spot size, the anode bevel, source-image receptor distance, object-image receptor distance, distance ratios, beam-part-film-alignment, geometric functions of positioning, and motion. Part IV, Comprehensive Technique, presents chapters on analyzing the radiographic image, simplifying and standardizing technique, technique by proportional anatomy, technique charts, exposure controls, patient dose, quality control, and solving multiple technique problems. Part V, Special Imaging Methods, includes mobile radiography, special imaging techniques, fluoroscopic image intensification, digital imaging, and computed radiography. Part VI, Processing the Radiograph, completes the text with chapters on processing steps and chemistry, developmental variables, automatic processors, film handling and duplication procedures, and sensitometry and darkroom control. Each chapter concludes with an examination that will help the student review materials and put them into perspective. Multiple choice, fill-in-the-blank, and identification/explanation questions are all included. An answer section is provided at the back of the text. This book is by far the the best available for schools that are focused on the practical application of radiographic technique. Its greatest strengths are its clear and concise explanations, plentiful examples, and abundant illustrations.
