Lasers have become integral to the modern practice of medicine in the fields of dermatology,
plastic surgery, otolaryngology, and phlebology. With the skin being the most accessible
organ in the body, many cutaneous disorders and conditions are ideally suited to
treatment by laser technology. Lasers are safely used to destroy or alter epidermal and
dermal processes and lesions comprising blood vessels or pigment.
I like playing around with words and letters. You probably know that
LASER is an artificial word derived from “Light Amplification by Stimulated
Emission of Radiation”. When starting my lecture on “Laser–Tissue Interactions”
I tend to write this derivation on the board. I continue with “LIGHT:
Lasers Irradiate Germinated and Healthy Tissues”.
Why? Lasers cut everything, if appropriate laser parameters are selected.
There is no shield around healthy tissue. And there is no laser that fits all sizes
as some clothes do. Lasers never have been some kind of wonder instruments.
In both the United Kingdom and the United States of America,
there is a legislative framework that assigns a very large measure
of responsibility to employers for the health and safety of their
employees. The detailed approach is slightly different and readers
need to familiarise themselves with the requirements. Where they
have doubts, they should consult the enforcing authorities for
• The Health and Safety Executive (United Kingdom)
• Occupational Safety and Health Administration (United States
The National Electrical Code is written as a minimum standard for
electrical installation for the protection of life and property. It does
not necessarily define the best installation methods, merely the minimum
safety standards. Many purchasers of electrical installations
will want to surpass the code.
In any complex undertaking there are fundamental issues that must
be mastered if the project is to be successful. For the wiring of a
house, those fundamentals are the safety of the installation and the
safety of the installer. Everything else follows from there.
Laser hair removal was performed experimentally for about 20 years before it became commercially available in the mid-1990s. One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998. The efficacy of laser hair removal is now generally accepted in the dermatology community, and laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment.
This volume consists of a collection of current studies on free electron lasers. Free
Electron Lasers covers the analysis of fundamentals and questions of design of these
devices functioning from the infrared to ultraviolet or xuv wavelength regimes. In
addition to the comparison with conventional lasers, analyses of some related topics
concerning near-field and cavity electrodynamics, compact and table-top
arrangements and strong radiation–induced exotic states of matter are presented.
This book is devoted to different sides of Biomedical Engineering and its applications in science and Industry. The covered topics include the Patient safety in medical technology management, Biomedical Optics and Lasers, Biomaterials, Rehabilitat, Ion Technologies, Therapeutic Lasers & Skin Welding Applications, Biomedical Instrument Aopplication and Biosensor and their principles.
In these days, it is impossible to think an area of knowledge that can keep on
developing without the make a collaboration in interdisiplinary fields.
Biomedcal Engineering is an interdisiplinary field that advances knowledge in
engineering, biology and medicine, and enhances people health through crossdisciplinary
actions that merge the all of the engineering disiplines with the
biomedical branch and clinical practice.
This document is historic for two major reasons. First, it represents the
first jointly authorized publication by both American Association of
Medical Physicists (AAPM) and American College of Medical Physics
(ACMP). This document began as a 1991 ACMP report. In 1997 the
General Medical Physics committee of AAPM invited Dr. Brahmavar,
who authored the original report, to chair a task group to rewrite and
update the document as an AAPM task group report. As it neared
completion, there was a suggestion that perhaps ACMP would be
interested in supporting the revised document.
