Medical Lasers and Their Safe Use


Book Description

This text was designed for the physicians, nurses, technical personnel, and staff members of medical facilities using lasers for surgical, therapeutic, and diagnostic purposes. The objective is to provide an understanding of the potential health and safety hazards associated with the use of medical laser systems and the precautions needed to use them safely. To do this, it is necessary to have an awareness of applicable standargs and regula tions that apply to laser use. This book is not intended as a substitute for the American National Standards Institute (ANSI) Z-136. 3, "Safe Use of Lasers in Health Care Facilities," but to facilitate its implementation as well as the implementation of the many other related regulations and guidelines that are pertinent. These other regulations include the Medical Device Amendments to the Food and Drug Act, the Federal Laser Product Performance Standards issued under the Radiation Control for Health and Safety Act, and applicable regulations of the Occupational Safety and Health Administration (OSHA). The text is organized to provide first an overview of laser hazards, laser surgical applications, and laser biological effects. General safety control measures and safety standards are then presented. Because laser tech nology is rapidly evolving, these general guidelines will allow safe use of new laser systems as they become available. Finally, specific safety guide lines and precautions are provided for specialized laser applications in the different health care specialties.




Safety with Lasers and Other Optical Sources


Book Description

Nearly a decade aga a general review article on the evaluation of optical radia tion hazards was published in Applied Optics (Sliney and Freasier, 1973). This arti cle received many favorable comments but also prompted many inquiries regarding specific optical hazard problems. From this it became evident that a monograph rather than a supplemental and expanded article was needed to fill this literature gap relating to laser and optical radiation hazards. The present work is designed to fill that gap, and is structured to permit either classroom or self-study use. Much of the material in this book was developed in eonnection with short courses on laser safety and radiometry in which we have participated, as weIl as from our previous articles. In particular, the sequenee of chapters is based upon the experiences which we have had in lecturing in courses with different schedules. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or physical scientist, while the review material on basic optical physics is intended more for the physician or life scientist.




Lasers for Medical Applications


Book Description

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. It provides a valuable contribution to laser medicine by outstanding experts in medicine and engineering. - Describes the interaction of laser light with tissue - Reviews every type of laser used in medicine: solid state, gas, dye and semiconductor - Describes the use of lasers for diagnostics

The first part introduces basic laser physics, including laser-tissue interactions as well as technical equipment and particular techniques developed for medical use in connection with laser. The second part of the text covers all areas of laser application in medicine and has been written by senior specialists from different countries. The book includes about 300 line drawings, more than 100 high quality photographs, an extensive subject and author register, and an exhaustive list of references.




Laser Safety


Book Description

Lasers perform many unique functions in a plethora of applications, but there are many inherent risks with this continually burgeoning technology. Laser Safety: Tools and Training presents simple, effective ways for users in a variety of facilities to evaluate the hazards of any laser procedure and ensure they are following documented laser safety standards. Designed for use as either a stand-alone volume or a supplement to Laser Safety Management, this text includes fundamental laser and laser safety information and critical laser use information rarely found in a single source. The first laser guide written by a working Laser Safety Officer (LSO), its depth and breadth make it appropriate for both the seasoned professional and the novice. It presents case studies of real accidents, preventive measures that could have been taken to avoid such accidents, and templates for documenting potential laser risks and attendant safety measures. Reflecting the exponential use of laser technology over the last several years, this text considers the growing use of petawatt laser installations and nanotechnology applications and addresses current laser projects such as the National Ignition Facility (NIF) and Linac Coherent Light Source (LCLS). Several chapters explore the components of laser work and laser safety that deal with optics, the optical table, the power meter, and user training. Ken Barat is the LSO for the Lawrence Berkeley National Laboratory, the first Department of Energy national lab. He also served as the LSO for the National Ignition Facility Directorate at Lawrence Livermore National Laboratory and is a member of the Laser Safety Forum in the United Kingdom. Internationally recognized, he has collected the wisdom of the top minds in the laser field to present a practical, straightforward handbook that helps those who work with lasers to harness their potential without endangering themselves or the people around them.

ANSI Z136. 1 Safe Use of Lasers (2014)


Book Description

The ANSI Z136.1 is a parent document and cornerstone of the Z136 series of laser safety standards, the Z136.1 is the foundation of laser safety programs for industrial, military, medical, and educational applications nationwide. Z136.1 provides guidance for the safe use of lasers and laser systems by defining control measures for each of seven laser hazard classifications. A practical means for accomplishing this is to (1) classify lasers and laser systems according to their relative hazards and to (2) specify appropriate controls for each classification Once a laser or laser system is properly classified, there should be no need to carry out tedious measurements or calculations to meet the provisions of this standard. However, technical information on measurements, calculations and biological effects is also provided within the standard and its appendixes.
