Those who are looking for an answer to the question «How is light used in medicine research?» often ask the following questions:

❓ How is light used in medicine?

  • Light therapy and phototherapy treatments involve the use of specific wavelengths of light to treat many medical conditions including mood disorders; skin disorders such as psoriasis, eczema, vitiligo , and acne; sleep disorders; wound healing; and photodynamic therapy (PDT).

❓ How light is used in medicine?

Known as phototherapy, the use of light in medical treatment is producing surprisingly successful results in the treatment of a variety of ailments from topical infections and chronic wounds to autoimmune and chronic degenerative diseases, says Chukuka S. Enwemeka, dean of the University of Wisconsin–Milwaukee’s College of Health Sciences.

❓ Are gamma photons used in medicine research?

Unlike alpha and beta particles, which have both energy and mass, gamma rays are just pure energy. 11 The penetrative power of gamma rays is such that several inches of a material such as lead, or several feet of concrete are required as a barrier to stop them. Gamma rays can pass through the whole human body easily, potentially causing severe damage to tissue and DNA.

Keywords used to search for articles included light, lighting, daylight, sunlight, healthcare, hospitals, depression, circadian rhythm, health, patients and nurses. Key findings: Light impacts human health and performance by enabling performance of visual tasks, controlling the body’s circadian system, affecting mood and perception, and by enabling critical chemical reactions in the body.

Light therapy and phototherapy treatments involve the use of specific wavelengths of light to treat many medical conditions including mood disorders; skin disorders such as psoriasis, eczema, vitiligo, and acne; sleep disorders; wound healing; and photodynamic therapy (PDT).

Another medical approach, also with argon lasers, is used to stop internal bleeding in patients. Green light is selectively absorbed by hemoglobin, the pigment in red blood cells, in order to seal off bleeding blood vessels. This can also be used in cancer treatment to destroy blood vessels entering a tumor and deprive it of nutrients.

In medicine, this translates into whether we expect the drug to increase or decrease the concentration of cholesterol, or if both could happen at the same time. In life sciences, there is usually some prior evidence of the expected effect of a drug before testing it in humans: in vitro , in animal experimentation, etc.

The 3D images are computer generated from a large number of projection images of the body recorded at different angles. SPECT imagers have gamma camera detectors that can detect the gamma ray emissions from the tracers that have been injected into the patient. Gamma rays are a form of light that moves at a different wavelength than visible light.

Identical wavelengths travel parallel to one another for reinforcement, creating a strong beam that can be focused down to less than 0.001 inch in diameter. Laser light can be controlled very precisely as a steady, continuous beam or in bursts or pulses. * Light Amplification by Stimulated Emission of Radiation.

Nanotechnology in Medicine Application: Antibacterial Treatments. Researchers at the University of Houston are developing a technique to kill bacteria using gold nanoparticles and infrared light. This method may lead to improved cleaning of instruments in hospital settings.

1.2 Biological effects of FIR. FIR application in medicine requires understanding and knowledge of the interactions of electromagnetic radiation at FIR range with biological structures (including cells, cell membranes, cell fluids – especially water, DNA/proteins) and functioning of the living systems in general.
