Summary : Lasers have a wide and growing range of applications in medicine. Lasers for Medical Applications summarises the wealth of recent research on the principles, technologies and application of lasers in diagnostics, therapy and surgery. Part one gives an overview of the use of lasers in medicine, key principles of lasers and radiation interactions with tissue. To understand the wide diversity and therefore the large possible choice of these devices for a specific diagnosis or treatment, the respective types of the laser (solid state, gas, dye, and semiconductor) are reviewed in part two. Part three describes diagnostic laser methods, for example optical coherence tomography, spectroscopy, optical biopsy, and time-resolved fluorescence polarization spectroscopy. Those methods help doctors to refine the scope of involvement of the particular body part or, for example, to specify the extent of a tumor. Part four concentrates on the therapeutic applications of laser radiation in particular branches of medicine, including ophthalmology, dermatology, cardiology, urology, gynecology, otorhinolaryngology (ORL), neurology, dentistry, orthopaedic surgery and cancer therapy, as well as laser coatings of implants. The final chapter includes the safety precautions with which the staff working with laser instruments must be familiar. With its distinguished editor and international team of contributors, this important book summarizes international achievements in the field of laser applications in medicine in the past 50 years.

Summary : The use of lasers in medical practice has dramatically increased over the years. Lasers and modern optics have largely been unexplored in medical science. This contributed work is both optimistic and cautionary in its expert evaluation of the state-of-the-art medical use of laser technology. The use of lasers to improve upon conventional practice is highlighted in the foreword by the late Dr. Leon Goldman, widely regarded as the father of laser medicine. Focused on filling a need for a "basic physics" understanding of laser-tissue interactions, Lasers in Medicine brings together contributions from experts in various medical specialties, including ophthalmology, dermatology, and cardiovascular medicine. Each chapter addresses significant applications of laser technology and offers the author's perspective on the state-of-the-art within that specialty. The discussions convey enough basic information to enable readers to assess a laser's usefulness for a specific purpose and to understand its limitations: A clinical engineer needs to know what laser to use for tattoo removal-Chapter 1 lists laser wavelengths available and pulse characteristics for absorption in tattoo ink to thermally decompose the ink, allowing the body to remove it. An oncologist discovers cancerous tissue in the lining of a bladder-can photodynamic therapy be used to treat it, and what is the success rate? Chapter 10 details treatment and Chapter 6 tells how to find exactly where the cancer is located. A newly graduated ophthalmologist needs to know the advantages a laser can bring to his profession-Chapter 8 can provide the information he needs to know. Lasers have made many advances in medicine-especially in ophthalmology, dermatology, and cardiology-sparking a wave of enthusiasm. Lasers in Medicine supplies sufficient fundamental knowledge in order to more appropriately assess a laser's usefulness for a specific purpose, and to not attempt to purchase or utilize a laser when it is not the best solution.

Summary : The use oflasers has entered almost every facet of medicine and biology. Therefore, it is to be expected that the reviews contained in this vol urne will reflect this diversity. As dinical acceptance has grown with various diagnostic and therapeutic applications, so has the need for a more thorough understanding of the theoretical background for each. This is especially true where a correlation is to be made between the theoretical background and the experimental data. It is only in this way that we can attain the optimal form of any therapy. The basic coupling ofenergy into biological tissue and its conversion into heat is characterized by many parameters. One ofthe most important is pulse duration. The review by Bimgruber in Chapter 6 shows how our knowledge ofthis parameter has been extended.The need for a more basic understanding of the interaction of electromagnetic energy with various kinds of materials has led to investigations on the nature of plasmas their stability and instability,and how theyexist. Docchio reviews the factors that cause them to occur at a specific locale and then to move away from that site. The availabilityofmany types ofoptical fibers has extended our ability to deliver laser energy from various types oflasers into almost anyselected location. This is particularly useful in medicine, where less invasive ap proaches to surgery and diagnosis are always helpful. However, as Rol and his colleagues explain, the power-handling capabilities ofoptical fibers limit many applications, particularly for short-duration, high-peak-power laser pulses.

Summary : In the intervening years since the publication of Volume I, the develop ment of new uses for the various types of lasers has proceeded at a rate more rapid than even the most fanciful dreamers envisioned. Of course, the main effort has been on the laser itself-new wavelengths, shorter and longer time domains for pulses, increases in power, and, most important, greater reliability. In its first stage the laser was described as a solution in search of a problem. The production of holograms was one problem whose solution seemed to involve large number of lasers. However that proposal had its own difficulties, for the hologram itself was described as a solution searching for a problem. But all of that now is a chapter from ancient history . On the current scene the laser is used in industrial pro duction lines, as a classroom item at all levels of education, and in com mercial usage such that the public is generally exposed to the laser devices themselves. Trial runs have been made, e. g. , of laser-based supermarket checkout devices and as commercial exploitation of this item begins, cer tainly many more similar adaptations will follow. However, the shift in emphasis from research usage of lasers to de velopment and production has been relative rather than absolute. The use of the laser in research has not lessened; rather it has grown at as fast a pace. Yet a similar trend is seen there also.

Summary : The laser has revolutionized many areas of science and society, providing bright and versatile light sources that transform the ways we investigate science and enables trillions of dollars of commerce. Now a second laser revolution is underway with pulsed petawatt-class lasers (1 petawatt: 1 million billion watts) that deliver nearly 100 times the total world's power concentrated into a pulse that lasts less than one-trillionth of a second. Such light sources create unique, extreme laboratory conditions that can accelerate and collide intense beams of elementary particles, drive nuclear reactions, heat matter to conditions found in stars, or even create matter out of the empty vacuum. These powerful lasers came largely from U.S. engineering, and the science and technology opportunities they enable were discussed in several previous National Academies' reports. Based on these advances, the principal research funding agencies in Europe and Asia began in the last decade to invest heavily in new facilities that will employ these high-intensity lasers for fundamental and applied science. No similar programs exist in the United States. Opportunities in Intense Ultrafast Lasers assesses the opportunities and recommends a path forward for possible U.S. investments in this area of science.

Summary : The laser's range of application is extraordinary. Arthur Schawlow says, "What instrument can shuck a bucket of oysters, correct typing errors, fuse atoms, lay a straight line for a garden bed, repair detached retinas, and drill holes in dia monds?"O The laser's specifically biomedical uses cover a similarly broad and interesting spectrum. In this book, I have endeavored to convey some of the fas cination that the laser has long held for me. It is my hope that both clinicians and researchers in the various medical and surgical specialties will find the book a use ful introduction. Biologists, particularly molecular biologists, should also find a great deal of relevant information herein. This volume's distinguished contributors provide admirably lucid discussions of laser principles, instrumentation, and current practice in their respective special ties. Safety, design, capabilities, and costs of various lasers are also reviewed. We have aimed to create a practical text that is comprehensive but not exhaustive. Our emphasis on the practical, rather than the esoteric, is dictated not only by the short history of biomedical laser use, but by the extent of the community to which this information will appeal.
