This comprehensive guide shows how to reduce the need for repeat radiographs. It teaches how to carefully evaluate an image, how to identify the improper positioning or technique that caused a poor image, and how to correct the problem. This text equips radiographers with the critical thinking skills needed to anticipate and adjust for positioning and technique challenges before a radiograph is taken, so they can produce the best possible diagnostic quality radiographs. Provides a complete guide to evaluating radiographs and troubleshooting positioning and technique errors, increasing the likelihood of getting a good image on the first try. Offers step-by-step descriptions of all evaluation criteria for every projection along with explanations of how to reposition or adjust technique to produce an acceptable image. Familiarizes technologists with what can go wrong, so they can avoid retakes and reduce radiation exposure for patients and themselves. Provides numerous critique images for evaluation, so that readers can study poor images and understand what factors contributed to their production and what adjustments need to be made. Combines coverage of both positioning and technique errors, as these are likely to occur together in the clinical environment. Student workbook available for separate purchase for more practice with critique of radiographs. Provides Evolve website with a course management platform for instructors who want to post course materials online. Expanded coverage to include technique and positioning adjustments required by computed radiography. Pediatric radiography, covering radiation protection and special problems of obtaining high-quality images of pediatric patients.

Exercises in trauma and non-routine radiography to correct poor-quality images in trauma and mobile situations.

Learn to produce the most accurate radiographic images on the first try with Radiographic Image Analysis, 4th Edition. This thoroughly updated guide walks you through the steps of how to carefully evaluate an image, how to identify the improper positioning or technique that caused a poor image, and how to correct the problem. For each procedure, there is a diagnostic-quality radiograph along with several examples of unacceptable radiographs, a complete list of radiographic evaluation guidelines, and detailed discussions on how each of the evaluation points is related to positioning and technique. Each unacceptable radiograph is accompanied by a description of the misaligned anatomical structures, how the patient was mis-positioned, and how to adjust technique to obtain an acceptable radiograph. "The whole text is well presented." Reviewed by Jenny May on behalf of Radiography, July 2015 Poorly positioned example images appear at the end of procedures to test your knowledge.

Thorough and easy to follow, this book is a complete guide to the accurate evaluation of radiographs for the most commonly performed orthopaedic procedures. Readers will learn how to adjust positioning and technical factors when unacceptable radiographs are obtained. Detailed discussions correlate each evaluating criteria with the patient or central ray setup procedure. An instructor's manual and slide set are available.

Radiological Imaging: The Theory of Image Formation, Detection, and Processing is intended to prepare the student to do research in radiological imaging, to teach general image science within a radiographic context, and to help the student gain fluency with the essential analytical tools of linear systems theory and the theory of stochastic processes that are applicable to any imaging system. The book contains chapters devoted to the discussion of linear systems, Poisson processes, analysis of radiographic systems, radiographic image detectors, and the various aspects of three-dimensional or tomographic imaging. Computed tomography, psychophysics, and scattered radiation and its effect on image are also elucidated. Radiology technicians will find the book very invaluable.

With the technology innovations dentistry has witnessed in all its branches over the past three decades, the need for more precise diagnostic tools and advanced imaging methods has become mandatory across the industry.
