Orthopedic devices improve the quality of life of millions of people, and show up on radiographs and cross-sectional imaging studies daily. This text will familiarise radiologists with the indications, applications, potential complications, and radiologic evaluation of many medical devices. The book offers a complete discussion of fracture fixation, joint arthroplasty, and orthopedic apparatus of the neck and spine, including the cervical, thoracic, and lumbar spine. It also provides detailed overviews of devices used for common dental disease, covers the general principles applicable to complications of orthopedic devices, foreign body ingestions, insertions and injuries, and details quality assurance issues concerning the manufacture and distribution of devices. Featuring a large gallery of apparatus for reference, an extensive glossary of terms and a list of manufacturers, Radiologic Guide to Orthopedic Devices is an essential resource for radiologists, orthopedists and emergency medicine physicians. Regular updates to the topics covered will be available on http://www.medapparatus.com.

The Barnard Objects have fascinated professional and amateur astronomers for over one hundred years. Many of those objects first imaged by E.E. Barnard on black-and-white photographic plates are now being captured daily in thousands of color astrophotographs. This book tells of Barnard’s story; describing his life and work as well as how the fields of astronomy and astrophotography have transformed ever since. The chapters in this book are equal parts history and science. It will provide readers with an introduction to nebula science and the incredible discoveries made in this field over the decades; including an overview of popular astronomical catalogues and a detailed look at how astronomical imaging has advanced since Barnard’s time, from early plates to digital imaging and chips. In addition, the book features a comprehensive guide to viewing and imaging these objects yourself. A glossary of astronomical and photographic terms is provided, along with detailed references. And, an updated table displaying the locations of these Barnard Objects; including the missing twenty-five objects from E.E. Barnard’s original catalogue. Richly researched and illustrated, this fascinating reference will attract astronomers of all skill levels interested in astrophotography and how it has changed over the past hundred years.
