Medical applications of laser ppt

Laser and its medical applications S. Other spectroscopic techniques based on lasers can be used to make extremely sensitive detectors of various molecules, able to measure molecular concentrations in the parts-per-trillion ( ppt ) level. Due to the high power densities achievable by lasers , beam-induced atomic emission is possible: this . In this chapter, we will discuss principal applications of lasers in modern medicine. Due to the present boom in developing new laser techniques and due to the limitations given by the dimensions of this book, not all disciplines and procedures can be taken into account.

The main intention is thus to focus on the most .

Very different types of lasers are required for medical applications , depending on the optical wavelength, output power, pulse format, etc. Lasers were first used medically in. In many cases, the laser wavelength is chosen such that certain substances (e.g. pigments in tattoos or caries in teeth) absorb light more strongly than surrounding tissue . Optical methods based on interactions of light with matter (biological sample). This is the interaction between the laser radiation and human tissue.

Because these motors use direct drive, they have virtually no friction and provide an extremely stiff mechanical system. With the availability of lasers , laser crystals, fiber. An example is the endoscope integrated system.

From the Greek endo means within and skopien,. Nanotechnology and advanced materials. High-tech industrial applications. Medical diagnostics and treatment technology.

Besides, laser has already brought great benefits in surgery, photography, . University of British Columbia. Saturday morning lecture series on Quantum Physics and Chemistry. Advantages : Wider field(ability to reach periphery) . Better visualization and laser application inhazy medium. Ability to treat in supine position. Difficulty to standardize spot size.
