Endovenous thermal ablation (EVTA) by radiofrequency or laser is a safe and effective treatment of refluxing great saphenous veins [7] (GSVs) and has replaced traditional high ligation and stripping in official recommendations of various leading Vascular Societies in the United States and the United Kingdom.
Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model. They are usually constructed of one or more glass prisms with dichroic optical ...
Small incision lenticule extraction. ReLEx Small incision lenticule extraction ( SMILE ), second generation of ReLEx Femtosecond lenticule extraction ( FLEx ), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism. Although similar to LASIK laser surgery, the intrastromal ...
v. t. e. Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps) and in Russia (in all variants).
1896 – French Dr. Victor Despeignes, "the father of radiation therapy", starts to use X-rays to treat cancer [8] 1896 – American Dr. Emil Grubbe starts to treat breast cancer patients with X-rays [4] 1896 Sir George Thomas Beatson invented hormonal treatment of breast cancer by bilateral ovary removal in women with inoperable breast cancer.
Diamond enhancements are specific treatments, performed on natural diamonds (usually those already cut and polished into gems ), which are designed to improve the visual gemological characteristics of the diamond in one or more ways. These include clarity treatments such as laser drilling to remove black carbon inclusions, fracture filling to ...
Proton therapy. In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer. The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence ...
A Glan–Taylor prism reflects s -polarized light at an internal air-gap, transmitting only the p -polarized component. The optical axes are vertical in the plane of the diagram. A Glan–Taylor prism is a type of prism which is used as a polarizer or polarizing beam splitter. [1] It is one of the most common types of modern polarizing prism.
