Laser-assisted drug delivery (LADD) is a drug delivery technique commonly used in the dermatology field that involves lasers. As skin acts as a protective barrier to the environment, the absorption of topical products through the epidermis is limited; thus, different drug delivery modalities have been employed to improve the efficacy of these treatments.
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
A Therac-25 had been in operation for six months in Marietta, Georgia at the Kennestone Regional Oncology Center when, on June 3, 1985, applied radiation therapy treatment following a lumpectomy was being performed on 61-year-old woman Katie Yarbrough. She was set to receive a 10-MeV dose of electron therapy to her clavicle. When therapy began ...
In nuclear physics, absorption of nuclear radiations can be used for measuring the fluid levels, densitometry or thickness measurements. [2] In scientific literature is known a system of mirrors and lenses that with a laser "can enable any material to absorb all light from a wide range of angles." [3]
Absorbed dose is a dose quantity which is the measure of the energy deposited in matter by ionizing radiation per unit mass.Absorbed dose is used in the calculation of dose uptake in living tissue in both radiation protection (reduction of harmful effects), and radiology (potential beneficial effects, for example in cancer treatment).
An other active research area of laser–matter interaction is the radiation pressure acceleration of ions or protons from thin–foil targets. [35] High ion energy beams can be generated for medical applications (for example in ion beam therapy [36]) by the radiation pressure of short laser pulses on ultra-thin foils.
Resolved sideband cooling is a laser-cooling technique that can be used to cool strongly trapped atoms to the quantum ground state of their motion. The atoms are usually precooled using the Doppler laser cooling. Subsequently, the resolved sideband cooling is used to cool the atoms beyond the Doppler cooling limit.
