My Active Debate

MRI technology:
Known advantages of using MRI:  it’s an important diagnostic tool because of its  abilities that help the physicians to identify any type of abnormal tissues in the human body without the usage of x-rays or play live blackjack, used before as the only way of examination. MRI is both safe and painless, and has no known side effects, typical for other means of diagnostics.

Infrared waves-heat lamps.

Infrared light or infrared radiation is invisible electromagnetic radiation with frequencies in the range from 0.74 microns to 1mm.Any heated body can be the source of infrared radiation. Many objects that are pure for usual visible light don’t let infrared radiation pass. For example a water layer several millimeters wide is not pure for infrared lights, while a piece of black paper is pure for infrared red. Infrared light is used in the medical diagnostics because it allows taking the temperature map of the human’s body and judging one’s health by this data.

The most simple transformer of infrared light to visible light is a device that has double glass walls and double bottom with no air in. On the inner side of the bottom there is partly transparent photo cathode and on the other side of the wall there is a luminescent screen. With a help of special lenses the image in infrared lights is projected on photo cathode.  By the influence of infrared beams photo cathode begins to emit electrons, moreover the intensity varies as the brightness of infrared beams varies as well.  Because of the high potential difference caused by high voltage applied between the screen and the cathode, the electrons accelerate and bombard the screen at the same time causing it’s luminary state. The intensity of the   luminescence of the separate dots on the screen depends on the stream of electrons density, as the result appears visible image of the testing object.

Red Light and infrared Light Therapy
As the research shows over 40 years the testing of red-light therapy and treatment had proved that it positively influenced human tissues on the cell level. Either visible red (400nm – 700nm) or invisible infrared light (700nm – 2000nm) appeared to show aproximately 24 different positive cell changes. Visible red light, with a  wavelength near 660 nm , penetrates into human tissue  cells as deep as  about 8-9 mm. It really helps  curing  skin problems among which are :wounds, cuts, scars, trigger points, or acupuncture points. It’s also   an effective mean of  infections treatment. Infrared light penetrates as deep as 30-40 mm which makes it very effective for treatment ofbones, joints, deep muscles, etc. Even though that ifrared light and red light penetrate to the different level of depth their influence and way of treatment are basically similar…
