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.

This comprehensive guide provides all the tools you need to accurately evaluate radiographic images and make the adjustments needed to acquire the best possible diagnostic quality images. You'll discover how to evaluate an image, identify any improper positioning or techniques that caused poor quality, and correct the problem. No other text is devoted to equipping you with the critical thinking skills needed to properly position patients for optimal radiographs and help minimize the need for repeat images. Chapter outlines give you an at-a-glance summary of chapter content Labeled images with analysis and correction help you develop your skills for producing optimal images, thus reducing the need for repeat procedures Student workbook provides additional opportunities to apply what you've learned in the text Expanded digital radiography content includes advances in digital imaging to keep you up-to-date in the field Chapter objectives help you master key content Quick reference tables highlight significant information More bone photographic images better illustrate difficult-to-evaluate procedures More pediatric and trauma images improve your ability to produce optimal images of different procedures

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. Evaluation criteria related to technique factors, which historically account for 60%-70% of retakes. New chapter on evaluation of images of the gastrointestinal system. Pitfalls of trauma and mobile imaging to encourage quick thinking and problem-solving in trauma situations. Improved page design and formatting to call attention to most important content.

An introduction to computer vision and associated digital processing functions. Reviews all aspects of image processing, pattern recognition, geometric optics, and artificial intelligence that are important to solving computer vision problems. Also provides an introduction to digital image acquisition and display, hardware, and techniques. Discusses special computer architectures for computer vision, new neural network applications, edge detection strategies, and segmentation.

Since several years, methods and entire systems have been developped to evaluate digitized picture data from rather different problem areas such as medicine, geological and earth resource investigations, sa­ tellite applications, and industrial automation to name but a few. As is to be expected, methodical approaches are usually first published in the context of the special application for which they have been de­ velopped. To intensify the exchange of know-how regarding the various methods across the boundaries of special application areas, the Technical Com­ mittee 6 of the Gesellschaft fur Informatik in cooperation with the Technical Committee 6 of the Nachrichtentechnische Gesellschaft in the VDE have organized a conference on Digitized Image Processing at Munich, March 28-30, 1977, the proceedings of which are presented in this v- ume. It is a pleasure to thank my colleagues J. Bodechtel, MUnchen R. Dierstein, Oberpfaffenhofen Th. Einsele, MUnchen P. Heintzen, Kiel H. Kazmierczak, Karlsruhe A. Schief, Karlsruhe J. SchUrmann, Ulm for their willingness to offer their time and cooperation under some­ what stringent boundary conditions in selecting the program for this conference. My special thanks are due to Prof. Bodechtel for his or­ ganizational effort to host the conference at his institute. May I mention that Munich with its world renown treasures of paintings provides the opportunity to experience some individual picture process­ ing of a kind which in my opinion is worth the effort even it is not digital.

Review, practice, and apply concepts of digital imaging and positioning! With chapters corresponding to the chapters in Radiographic Image Analysis, 6th Edition, this practical workbook provides projections and questions to help you hone your imaging and evaluation skills. Exercises for each procedure ask you to correct positioning errors, practice critical thinking, and solve positioning challenges. Adding evaluation images beyond those in the main text, this workbook helps you prepare for success on the ARRT® certification examination and in radiography practice. - Positioning and technique exercises help with knowledge retention and prepare you for success in radiography practice. - Study questions for each procedure focus on how the patient should be positioned to obtain an accurately positioned projection, and help you prepare for the ARRT® certification examination. - Poorly positioned projections not included in the textbook focus on each topic and procedure, and ask you to find the cause of the problem. - Questions on improperly positioned projections ask you to evaluate the image and make adjustments when the images are suboptimal. - Answer key to the study questions may be found on the Evolve website for Radiographic Image Analysis, under student resources. - NEW! Updated content reflects the changes and new information in the 6th edition of Radiographic Image Analysis.
