Textbook of Radiographic Positioning and Related Anatomy


Kenneth L. Bontrager - 1987
    It presents positioning and projection information in an easy-to-read, bulleted format on one side of the page spread, with corresponding positioning photos, radiographic images and anatomical drawings on the other side. Expert content covers pathology, geriatric and pediatric patient populations, survey information, and 100 new positioning photographs for the latest in radiographic positioning. The 6th edition contains a new chapter on digital imaging, and digital imaging information is incorporated where appropriate throughout the book. New photographs and redrawn illustrations create a consistent, visual appearance throughout the book.- Characterized by a clear, easy-to-follow organization that features one projection per page. Positioning and projection information is presented in an easy-to-read bulleted format on the left side of the page, and positioning photos, radiographic images and anatomical drawings are aligned on the right. This show and tell style helps students visualize anatomy and understand positioning.- Includes about 200 of the most commonly requested projections. Competency in performing these projections is necessary for all entry-level practitioners. By contrast, Merrill's Atlas includes over 400 projections and much more information on advanced imaging.- Critique Radiographs provide the basis of classroom or lab discussion. The WB/LM contains questions specific to these radiographs.- Pathologic Indications in appropriate chapters - Introducing pathology with positioning helps students understand the whole patient and improves their ability to produce radiographs that make diagnosis easy for the physician.- Pediatric Applications in appropriate chapters prepare technologists to deal competently with the special needs of their pediatric patients.- Geriatric Applications in appropriate chapters - Important information for technologists to understand the varying needs of their patient base.- Alternative Modalities or procedures inform students of which projections can better demonstrate certain anatomical parts or pathology, or which may be necessary if patient is unable to cooperate fully.- Radiographic Criteria on positioning pages help students develop a routine for evaluating radiographic quality.- Pathology Demonstrated provides students with a larger frame of reference, and therefore a greater understanding, of each projectionA new chapter on digital imaging discusses basic principles, applications, and image quality - digital imaging information essential for making appropriate positioning adjustments - to ensure readers are prepared to encounter new technology in clinical practice.Content updates include a totally new section on surgical radiography, new sections in all chapters on digital imaging considerations, an expanded section on bone densitometry, and a new introduction to positron emission tomography (PET).Updated and revised chapters cover angiography and interventional procedures, and computed tomography.More than 150 new positioning photos, in addition to many updated images, complement the new material.

Twenty Small Sailboats to Take You Anywhere


John Vigor - 1999
    But what was once fantasy is now reality. With a growing glut of good used boats on the market, its possible to sail around the world in a boat that costs less than a car. In this fascinating book, well-known boating author John Vigor turns the spotlight on 20 seaworthy sailboats that are at home on the ocean. These are old fiberglass boats, mostly of traditional design and strong construction. All are small their sizes range from 20 feet to 32 feet overall but all have crossed oceans. Many have circumnavigated the world. And all are inexpensive. There are many hundreds of small cruising boats sailing the seven seas at this moment. They explore everywhere, from the ice-bound shores of Antarctica to the high latitudes of the Northern Hemisphere. Most, however, ply the tradewind routes where flying fish play. The water is warm, and coconut trees line calm lagoons bounded by beaches of pure white sand. But choosing the right boat to cross an ocean or go around the world can be a confusing and exasperating experience, particularly if your budget is tight. Its well-nigh impossible to find objective comparisons. Vigor sets out to remedy that in this book. He compares the designs and handling characteristics of 20 different boats whose prices on the secondhand market start at about $3,000. Interviews with experienced owners (featuring valuable tips about handling each boat in heavy weather) are interspersed with line drawings of hulls, sailplans, and accommodations. Vigor has unearthed the known weaknesses of each boat and explains how to deal with them. He rates their comparative seaworthiness, their speed, and the number of people they can carry in comfort. If you have ever dreamed the dream, this is the book that will turn it into reality.
