Visual Plague: The Emergence of Epidemic Photography
by Christos LynterisHow epidemic photography during a global pandemic of bubonic plague contributed to the development of modern epidemiology and our concept of the &“pandemic.&”In Visual Plague, Christos Lynteris examines the emergence of epidemic photography during the third plague pandemic (1894–1959), a global pandemic of bubonic plague that led to over twelve million deaths. Unlike medical photography, epidemic photography was not exclusively, or even primarily, concerned with exposing the patient&’s body or medical examinations and operations. Instead, it played a key role in reconceptualizing infectious diseases by visualizing the &“pandemic&” as a new concept and structure of experience—one that frames and responds to the smallest local outbreak of an infectious disease as an event of global importance and consequence. As the third plague pandemic struck more and more countries, the international circulation of plague photographs in the press generated an unprecedented spectacle of imminent global threat. Nothing contributed to this sense of global interconnectedness, anticipation, and fear more than photography. Exploring the impact of epidemic photography at the time of its emergence, Lynteris highlights its entanglement with colonial politics, epistemologies, and aesthetics, as well as with major shifts in epidemiological thinking and public health practice. He explores the characteristics, uses, and impact of epidemic photography and how it differs from the general corpus of medical photography. The new photography was used not simply to visualize or illustrate a pandemic, but to articulate, respond to, and unsettle key questions of epidemiology and epidemic control, as well as to foster the notion of the &“pandemic,&” which continues to affect our lives today.
Visual Prosthesis: A Concise Guide
by Jeffrey N. WeissFor the millions of people with untreatable blindness the thought of a visual prosthesis that would allow them to live a normal life has always been a distant hope.

Visual Tracking in Conventional Minimally Invasive Surgery
by Shahram PayandehVisual Tracking in Conventional Minimally Invasive Surgery introduces the various tools and methodologies that can be used to enhance a conventional surgical setup with some degree of automation. The main focus of this book is on methods for tracking surgical tools and how they can be used to assist the surgeon during the surgical operation. Various notions associated with surgeon–computer interfaces and image-guided navigation are explored, with a range of experimental results. The book starts with some basic motivations for minimally invasive surgery and states the various distinctions between robotic and non-robotic (conventional) versions of this procedure. Common components of this type of operation are presented with a review of the literature addressing the automation aspects of such a setup. Examples of tracking results are shown for both motion and gesture recognition of surgical tools, which can be used as part of the surgeon–computer interface. In the case of marker-less tracking, where no special visual markers can be added to the surgical tools, the tracking results are divided into two types of methodology, depending on the nature and the estimate of the visual noise. Details of the tracking methods are presented using standard Kalman filters and particle filters. The last part of the book provides approaches for tracking a region on the surgical scene defined by the surgeon. Examples of how these tracking approaches can be used as part of image-guided navigation are demonstrated. This book is designed for control engineers interested in visual tracking, computer vision researchers and system designers involved with surgical automation, as well as surgeons, biomedical engineers, and robotic researchers.

Visualising Health Care Practice Improvement: Innovation from Within
by Jessica Mesman Rick Iedema Katherine CarrollWhy is it that in spite of all the health policy reforms, clinical practice innovations, increasing intersectoral interdependencies and new medical and information technologies, so little has changed in the way we research and evaluate health care? Don't these changes cry out for new ways of being studied and appraised? And don't our approaches to clinical practice innovation cry out for being reinvented too? Surely, we cannot continue to wheel out research and evaluation paradigms, improvement approaches and methods that were designed for 20th century problems and 20th century health care, and assume they will be able to make sense of the problems we experience and the care we provide in the 21st century? These changes necessitate a new paradigm of health service research, evaluation and improvement and this new model adopts approaches and methods that embrace complexity. The approaches and methods can account for the vicissitudes of front-line care, the activities of front-line staff and the experiences of patients and families - where care happens. Visualising Health Care Practice Improvement draws on years of video feedback research shaping an approach that enables not only a retrospective understanding but also a view into the future, of what might be possible. It presents the argument that change is not principally about adopting solutions from elsewhere but that it is conditional on people exploring whether proposed solutions suit existing habituations. It involves a process of exploration, discovery, secession and renewal. Health care managers, policy makers and shapers will find this book enlightening. It will also be empowering to all health care professionals and front-line staff.

Visualizing Immunity
by Dorian Mcgavern Michael DustinThe immune system is not bound by a single tissue but is instead bestowed with the challenge of warding off invading pathogens throughout the body. Constant surveillance of the body requires that the immune system be highly mobile and able to purge pathogens from all tissues. Because each tissue presents its own unique architecture and milieu, it is necessary for the immune system to be as malleable as it is dynamic. For example, how the immune system handles a pathogen in the lung can differ significantly from a pathogen encountered in the gut. Understanding immune complexity in diverse tissue environments is a challenge for researchers. However, advances in imaging have greatly improved our ability to probe the immune system. From snap-shots in time to 4D movies, imaging systems have been used to generate stunning visualizations of immune cells in action throughout the body. These visualizations are not only aesthetically pleasing but they have yielded great advances in our understanding of immune function. This volume provides a synopsis of major insights in immunology revealed using imaging approaches. "Seeing is truly believing", and this volume was assembled to recognize past accomplishments and to provide visions of what the future holds in store in this exciting field.

Vital Conversations: Improving Communication Between Doctors and Patients
by Dennis RosenThe health-care system in the United States is by far the most expensive in the world, yet its outcomes are decidedly mediocre in comparison with those of other countries. Poor communication between doctors and patients, Dennis Rosen argues, is at the heart of this disparity, a pervasive problem that damages the well-being of the patient and the integrity of the health-care system and society. Drawing upon research in biomedicine, sociology, and anthropology and integrating personal stories from his medical practice in three different countries (and as a patient), Rosen shows how important good communication between physicians and patients is to high-quality—and less-expensive—care. Without it, treatment adherence and preventive services decline, and the rates of medical complications, hospital readmissions, and unnecessary testing and procedures rise. Rosen illustrates the consequences of these problems from both the caregiver and patient perspectives and explores the socioeconomic and cultural factors that cause important information to be literally lost in translation. He concludes with a prescriptive chapter aimed at building the cultural competencies and communication skills necessary for higher-quality, less-expensive care, making it more satisfying for all involved.
