Diathermy is used in physical therapy to deliver moderate heat directly to pathologic lesions in the deeper tissues of the body. Surgically, the extreme heat that can be produced by diathermy may be used to destroy neoplasms, warts, and infected tissues, and to cauterize blood vessels to prevent excessive bleeding.
In condensed-matter physics, channelling (or channeling) is the process that constrains the path of a charged particle in a crystalline solid. [1] [2] [3]Many physical phenomena can occur when a charged particle is incident upon a solid target, e.g., elastic scattering, inelastic energy-loss processes, secondary-electron emission, electromagnetic radiation, nuclear reactions, etc.
Diathermy is produced by two techniques: short-wave radio frequencies in the range 1–100 MHz (shortwave diathermy) or microwaves typically in the 915 MHz or 2.45 GHz bands (microwave diathermy), the methods differing mainly in their penetration capability. [4] [5] [6] It exerts physical effects and elicits a spectrum of physiological responses.
Another method is known as thermolysis, also called radio frequency (RF), shortwave or diathermy. Thermolysis was developed in the 1920s and first reported in medical literature by Henri Bordier. [2] A thermolytic hair remover is essentially a radio transmitter, usually with an output of about 0–8 watts at a frequency of 13.56 MHz. RF energy ...
The first surgical procedures to reduce intraocular pressure of the eye, by decreasing production of aqueous humor, by damaging the ciliary body by diathermy, penetrating cyclodiathermy or surgical excision was done in the early twentieth century. [1] Cyclodestruction by diathermy was first performed by Weve in 1933. [11]
Localized hyperthermia treatment is a well-established cancer treatment method with a simple basic principle: If a temperature elevation to 40 °C (104 °F) can be maintained for one hour within a cancer tumor, the cancer cells will be destroyed. [11] The schedule for treatments has varied between study centers.
Known side effects and risks include the need for anesthesia, the risk of infection, and a risk of adhesions forming. [8] There may sometimes be a smaller risk of the person losing ovarian function. [8] Ovarian drilling is a surgical alternative to CC treatment or recommended for women with WHO Group II ovulation disorders. [6]
The Emission Channeling with Short-Lived Isotopes (EC-SLI) experiment is a permanent setup located within the ISOLDE facility and CERN. The purpose of the experiment is to study lattice locations of dopants and impurities in both single crystals and epitaxial thin films .
