Book Description
"A laboratory study was conducted to determine the relative effectiveness of various concepts for the display of information in the periphery. Two commercially available display systems were investigated in conjunction with other concepts involving the use of flicker to encode airspeed signals and differential brightness to enhance the discriminability of input signals. Displays were designed to present tracking information in three control dimensions; viz., pitch, roll and airspeed. An adaptive loop simulator was employed to evaluate operator performance. The results of the study clearly indicated that effective control can be exercised using peripheral displays employing changes in motion as the primary encoding stimulus. A higher level of performance was achieved with one system which contained a single display for presenting integrated pitch and roll signals. The addition of airspeed was found to degrade performance in pitch and roll under all display conditions. Performance could not be enhanced by means of differential brightness. Further evidence was provided for the use of motion as a very effective means for encoding displays designed for viewing in the periphery."--Abstract.

Book Description
"A study was conducted to determine the effectiveness of peripheral vision displays for presenting dynamic tracking information during difficult control tasks such as landing high speed aircraft or rendezvousing spacecraft. Based on a review of the literature, it was hypothesized that peripheral displays could be successfully used to improve performance provided visual switching between information sources is normally an essential part of such tasks. Visual switching consists of eye movement, accommodation, and convergence. The hypothesis was tested in the laboratory by comparing operator performance on a two dimensional compensatory tracking task under conditions in which the requirements for visual switching and the provisions of peripheral displays were systematically varied and controlled. It was clearly demonstrated that tracking performance deteriorates as visual switching increases and that peripheral displays can be used to overcome its adverse effects."--Abstract

Book Description
Recent vision research has led to the emergence of new techniques that offer exciting potential for a more complete assessment of vision in clinical, industrial, and military settings. Emergent Techniques for Assessment of Visual Performance examines four areas of vision testing that offer potential for improved assessment of visual capability including: contrast sensitivity function, dark-focus of accommodation, dynamic visual acuity and dynamic depth tracking, and ambient and focal vision. In contrast to studies of accepted practices, this report focuses on emerging techniques that could help determine whether people have the vision necessary to do their jobs. In addition to examining some of these emerging techniques, the report identifies their usefulness in predicting performance on other visual and visual-motor tasks, and makes recommendations for future research. Emergent Techniques for Assessment of Visual Performance provides summary recommendations for research that will have significant value and policy implications for the next 5 to 10 years. The content and conclusions of this report can serve as a useful resource for those responsible for screening industrial and military visual function.

Book Description
An up-to-date edition of the authoritative text on the physics of medical imaging, written in an accessible format The extensively revised fifth edition of Hendee's Medical Imaging Physics, offers a guide to the principles, technologies, and procedures of medical imaging. Comprehensive in scope, the text contains coverage of all aspects of image formation in modern medical imaging modalities including radiography, fluoroscopy, computed tomography, nuclear imaging, magnetic resonance imaging, and ultrasound. Since the publication of the fourth edition, there have been major advances in the techniques and instrumentation used in the ever-changing field of medical imaging. The fifth edition offers a comprehensive reflection of these advances including digital projection imaging techniques, nuclear imaging technologies, new CT and MR imaging methods, and ultrasound applications. The new edition also takes a radical strategy in organization of the content, offering the fundamentals common to most imaging methods in Part I of the book, and application of those fundamentals in specific imaging modalities in Part II. These fundamentals also include notable updates and new content including radiobiology, anatomy and physiology relevant to medical imaging, imaging science, image processing, image display, and information technologies. The book makes an attempt to make complex content in accessible format with limited mathematical formulation. The book is aimed to be accessible by most professionals with lay readers interested in the subject. The book is also designed to be of utility for imaging physicians and residents, medical physics students, and medical physicists and radiologic technologists perpetrating for certification examinations. The revised fifth edition of Hendee's Medical Imaging Physics continues to offer the essential information and insights needed to understand the principles, the technologies, and procedures used in medical imaging.
