Microscopes, first used in medicine in 1653, have been the standard lab tool for hundreds of years, and remains today the most important diagnostic device at our disposal. The new generation of miniature microscopes, however, has radically improved the ability of scientists and pathologists to view amazingly clear, high-resolution images of human tissue "in vivo." The new technology not only advances early disease detection considerably, but now also allows physicians to recognize and treat health problems in real time, at the point of diagnosis/point of care, in a non-invasive procedure. This revolution in microscopy has huge implications for progress in telepathology and telemedicine — Two fields that are exploding in the brave new world of digital medicine.This book will be the first to provide a comprehensive but concise update on the use of the new microscopic technology across the major body systems (cardiovascular, gastrointestinal, genitourinary, etc.), with a logical focus on cancer. It will describe both the science and the practical in vivo application of microscopy and the consequent closer translational collaboration between the pathologist/researcher and the physician. Contributions from expert diagnosticians will present a complete picture of the state of the art of IVM.
